An acid is a substance that produces H+ to form a solution that has a pH <7. It turns litmus paper red. It reacts with bases to form a salt and water. A weak acid is an acid that dissociates incompletely, releasing only some of its protons(H+). A strong acid is an acid that fully dissociates incompletely, releasing only some of its protons(H+).
A base is a substance that can accept (H+) and releases(OH-) to form a solution that has a pH>7. It turns litmus paper blue. It reacts with acids to form a salt and water.
A salt is a compound made from an acid when a metal takes the place of the hydrogen in the acid. Some salts dissolve in water easily. They are said to be soluble. Other salts do not dissolve at all. They are said to be insoluble. (Example: sodium sulfate)
A usual salt is produced by the whole alternate of the hydrogen ion of an acid by a basic essential while an acid salt is produced by the incomplete alternate of the hydrogen ion of an acid by a necessary thorough.
All acids are formed in a different way, as each involves different compounds. There are many chemical companies that create acids- some absorb heat, difficult-to-find chemicals, catalysts, etc, which is the cause it is hard to quantify how acids in specific are formed.
Which methods are used to prepare your chosen acid/base/salt? (Citric Acid)
1-Obtain citric acid in crystalline powder form. You can find this at many grocery stores, cooking stores or bulk food stores. Buy at least 1 lb. (454 g) in order to make an adequate amount of citric acid solution
2-Decide the quantity of citric acid powder to water that you require to make the solution.
3-Calculate the powder. Place 1 lb. (454 g) of citric acid powder in a non-metallic pot. Set the pot aside.
4-Boil...

Interesting facts:
-Citric acid (E330) and ascorbic acid both occur naturally in citrus fruits, but there is no vitamin C in citric acid.
-Chemically, the only difference between ascorbic acid and citric acid is one additional oxygen atom in citric acid.
-Unfortunately, vitamin C is very easily lost from fruits and vegetables when processed. That’s why in many products it is reintroduced as an additive.
-Citric acid makes it easier for the body to absorb some minerals. For example, calcium citrate is sometimes added to orange juice.
-Vitamin C tastes very bitter, just like most vitamins. In some cases Citric acid is used to mask the bitter flavor of vitamin C pills.
Each subsequent trial will use one gram more. 2.Put baking soda into reaction vessel. 3.Measure 40 mL vinegar. 4.Completely fill 1000 mL graduated cylinder with water.
need is water and an ester and we will end up with an organic acid produced as
Therefore, extensive research was carried on for the maximum protection of vitamin C maintaining the stability, pH sensitivity and permeation to the skin.
Citrus fruits such as oranges and grapefruit and their juices are rich in vitamin C. Broccoli, strawberries, cantaloupe, baked potatoes, and tomatoes are rich with Vitamin C. Vitamin C deficiency is rare. For those people who do not get enough vitamin C, they result with Vitamin C deficiency, which means lacking of sufficient amount of vitamin C in diet. Overtime, lacking of vitamin C cause the inability to form new collagen. This causes breaking down various tissues in our bodies, which affects tissues' repair and health. Scurvy is one of the serious disease that comes out with vitamin C deficiency. This disease causes various tissues sign and symptoms such as: fatigue, inflammation of the gums, small red or purple spots on the skin, joint pain, poor wound healing, corkscrew hairs, swelling , bleeding gums and loosening or loss of teeth is an example. Also, Rickets, Beriberi and Pellagra are names of diseases that caused by lack of vitamin
Vitamin C in the body acts as an antioxidant. Vitamin C loses electrons easily, a characteristic that allows it to perform as an antioxidant. In the body, antioxidants defend against free radicals. A free radical is a molecule with one or more unpaired electrons, which makes it unstable and highly reactive. By donating an electron or two, antioxidants neutralize free radicals and protect other substances from their damage. Figure 1 illustrates how vitamin C can give up electrons to stop free radical damage and then accept them again to become reactivated. This recycling of vitamin C is key to limiting losses and maintaining a reserve of
Apple cider vinegar (ACV) is made via crushing organically grown apples and permitting them to mature in wood barrels. Cider is a non-alcoholic, unsweetened beverage crafted from apples. The apple cider carries the sugar that is broken down into alcohol with yeast and micro organism at some stage in the fermentation technique. Then, it's miles was vinegar. ACV is a remarkable natural bacteria-combating agent containing many crucial minerals & hint elements which include calcium, potassium, magnesium, chlorine, phosphorous, sodium, copper, iron, sulfur, silicon and fluorine, all of which might be important for a wholesome frame. It is also an powerful remedy for some troubles associated with splendor. hence, in this text,

Vitamin C also known as ascorbic acid is needed for growth and maintenance of healthy tissues, especially skin, blood vessels, bones, gums, teeth. Vitamin C aids in resistance against infection and healing of wounds. It also helps the body absorb iron from food. Vitamin C can be found in green vegetables, potatoes, tomatoes and citrus fruits such as oranges and lemon. A lack of vitamin C can cause scurvy, iron deficiency and poor wound healing. A healthy diet should include a high amount of vitamin C because the human body cannot produce its own vitamin C.
When one hears the three words: vitamins, nutrients, and minerals, they think of one thing-being healthy and noticing what your intake is daily. Nutrition is all about vitamins and nutrients. Firstly, vitamins are an organic compound required by the body in small amounts of metabolism, to protect health, and for proper growth of children. Vitamins also assist in the formation of hormones, blood cells, nervous systems chemicals, and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified vitamins are: A, D, E, and K-fat contained foods, B, C-consumed immediately. A well known and commonly used in commercials for orange juice vitamin is vitamin C. Vitamin C or ascorbic acid is important in the synthesis and maintenance of connective tissues. The lack of vitamin C will result in a sickness called scurvy. Scurvy harms the gums, mucous membranes, and the skin. Another well-known vitamin and is also used to commercial to give more information about this beverage is the vitamin in milk. The vitamin in milk is vitamin D. If you do not drink milk and obtain this vitamin, your bones and teeth will become soft and weak. Lacking one or more of the 13 well-identified vitamins will cause sickness and weakness to your body. Secondly, nutrients are how the body assimilates certain compounds. Nutrients are classified in 5 major groups: proteins, carbohydrates, fats, vitamins, and minerals. One of the five nutrients is carbohydrate. The carbohydrate group principally consists of sugar, starch, dextrin, cellulose, and glycogen. In more basic terms, carbohydrates are sugars needed by human and other living organisms. Some types of foods that contain carbohydrates would be candies, ice cream, fruit juice, soda, chocolate bars etc. Lastly, vitamins are connected to minerals. Minerals are also a very important part of a healthy person. There are 11 major groups of minerals. They are: calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. All these terms look very familiar if one has taken chemistry. These are the elements of our world. One of the more common minerals that most people have heard of is calcium. Calcium also helps with the structure and strength of teeth and bones. Vitamins and minerals work together to help humans maintain a healthy body. For example, vitamin D works with calcium to help for and maintain the strength of teeth and bones.

vii. This would allow the determination of the percentage of citric acid in the lemon juice specifically, rather than the total acidity. The results of this could have been compared to those of the titration, and the contribution of citric acid to the overall initial acidity could have been determined.

Nowadays, healthy is the number one individual and also governmental concern. As the saying goes, ‘an apple a day keeps the doctor away’ is clearly show that eat nutritious food such as fruits and vegetables can provide a good health and can prevent us from harmful diseases. As we know, vegetables provided various types of vitamins needed by the body for instance pumpkin contains a lot of vitamin A, tomatoes contain vitamin C and spinach contains folate. Pumpkin is one of nature’s riches sources of alpha-carotene, a carotenoid that converts to retinol which is a form of vitamin A. The amount of vitamin A that contain in the pumpkin per serving (116g) is 171%, vitamin C 17%, calcium 2% and iron 5% (Pumpkin raw, 2014). There are a lot of benefits when consuming vitamin A, for example this vitamin promotes healthy vision, bone growth, reproduction and help boosts our immune system. Apart from that, a diet high in vitamin A may lower the risk of many types of cancer. Besides, some vegetables also contain a lot of vitamin C such as tomatoes, bell peppers and broccoli. The function of vitamin C is it helps heal the wounds and keep away the body from bacterial infection. According to researchers at Albert Einstein College of Medicine of Yeshiva University, they discovered that vitamin C can kill drug-resistant tuberculosis (TB) bacteria (Libov, 2013, para. 3). Besides that, vitamin C
Vitamins, a group of organic substances required in our diets in small amounts for growth and nutrition, are usually found in foodstuffs or taken as supplements. Yet vitamins probably present a wider gap between myth and reality in the layman's understanding than almost any other area of our diet. Surveys have found that while a majority of Americans do take vitamin supplements on a regular or occasional basis for reason of health concerns, there exists enormous confusion about the actual purpose and benefits of this practice ("Use of Vitamin and Mineral Supplements in the United States," 1990:161). Most people have a recognition that Vitamin C prevents scurvy, that Vitamin A is found in fish-liver oils, or that Vitamin D is found in dairy products; many people believe that Vitamin E preserves youth and prevents sterility, or that Vitamin C can present colds and cancer. Beyond this, however, there is still considerable ignorance and widespread myth.
