The effect of baking soda and vinegar reacting to the balloon. In this experiment, a scientist will observe how a balloon will inflate by using vinegar and baking soda. Both Vinegar and baking soda react to make the balloon blow up by using a different amount of both ingredients. The amount of baking soda and vinegar effecting of the balloon.The independent variable is the amount of vinegar and baking soda. The dependent variable is the radius of the balloon. The scientist will test if there is more baking soda in the balloon then the balloon will inflate to be bigger because baking soda has carbon dioxide which is a type of air that can be used to inflate the balloon. To be able to find the radius of the balloon, we will need to use …show more content…
Baking soda is it is a salt composed of sodium ions and bicarbonate ions and vinegar is a sour-tasting liquid containing acetic acid. “Baking soda and vinegar react with each other because of an acid-base reaction.Baking soda is a bicarbonate (NaHCO3) and vinegar is an acetic acid (HCH3COO). One of the products this reaction creates is carbon dioxide.”(coolscienceexperiments.com) The vinegar has lost H+ and becomes acetate, which pairs with the sodium from the baking soda (the sodium is just floating around in the watery liquid, but it likes to hang out with acetate!). This carbon dioxide will escape into the air as bubbles or foam, and it is this gas you can use to blow up a balloon!The chemical reaction caused by mixing baking soda and vinegar can cause balloons to race, homemade volcanoes to erupt and bubbles galore. Balloons are often used in baking soda and vinegar experiments because you can see the result of the chemical reaction.When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon. The more gas that is created, the larger the balloon will
Alka-Seltzer is made up of baking soda, aspirin, and citric acid which gives the tablet the fizz when dropped in any temperature water. “Alka-Seltzer is a medication that works as a pain reliever and an antacid. (Antacids help neutralize stomach acidity, which can cause heartburn.)” (Science Buddies, Carbonation Countdown: The Effect of Temperature on Reaction Time). To take the Alka-Seltzer tablet you have to dissolve it in water causing a chemical reaction to form and the whole solution begins to fizz. The fizz occurs since when you drop the tablet in the water the baking soda and the citric acid react causing the water to fizz also “sodium bicarbonate splits apart to form sodium and bicarbonate ions” (Science Buddies, Carbonation Countdown: The Effect of Temperature on Reaction Time). When the Alka-Seltzer is dropped in the water then a chemical reaction forms allowing the Alka-Seltzer to dissolve. Temperature is related to this experiment because the temperature affects how fast the hydrogen ions react with the bicarbonate ions and as the temperature increases the movement of the molecules increases in speed and vice versa (Science Buddies, Carbonation Countdown: The Effect of Temperature on Reaction Time).
...ost likely to be battery acid. If it is water, it has a Ph level of around 7. For vinegar, the Ph level is approximately 2.4 - 3.4. Thus, once testing the liquid compare it with the Ph levels above to discover the mystery solution.
Baking Soda and Vinegar: Limiting Reactant Lab Background The limiting reactant of a chemical reaction is the substance that places an upper bound on the amount of product that the reaction can produce. The limiting reactant places this upper bound because the reaction must stop once all of the limiting reactant is consumed. If the relative amount of reactants is altered, then the limiting reactant may change accordingly.
Constant: the dependent variable was the size of the gummy bear after it was soaked in regular water, salt water, baking soda water,and vinegar.
Independent variables There are many independent variables (which can also be called the manipulated variable- the variable that is varied in the investigation), but I will only vary two of them: the height the ball is dropped, The surface material the ball is dropped on will also be changed. Other variables that could be changed are: -mass of ball -air resistance (this may occur when the ball is dropped from greater heights) -ball material -gradient of surface -size of ball -kind of ball -ball density Dependent variables The dependent or responding variable is the variable that occurs due to factors that are changed in the independent or manipulated variables. If the independent variable is changed, this would affect the dependent variable.
I predict that if I double the amount of yeast then I will get double the amount of oxygen produced because I am doubling the rate of which the particles collide. I predict that if I double the amount of water in the yeast then the oxygen will have decreased by double because I am halving the amount of yeast particles the can react. Independent Variable = ==
In this experiment, the calcium carbonate was in the form of marble chips. The calcium carbonate reacted with hydrochloric acid when the acid was poured into marble chips. Due to calcium carbonate’s higher reactivity, it displaced hydrogen in the hydrochloric acid. As a result, products of calcium chloride, carbon dioxide and water were formed. As the chemical reaction occurred, the water in the measuring cylinder was displaced and gas bubbles that were blowing out represented carbon dioxide.
Out of these variables I will use concentration as my input variable and amount of carbon dioxide released as my outcome variable. You can see how I will use and measure these variables in the method section of this investigation. My preliminary results can be found in appendix 1. These show what measurements of the input variables I decided to use and why I decided this.
The dependent variable that will be measured is the height at which the ball bounces back. The control variables that will need to be kept constant if the results are to be as accurate as possible are. 1. What is the difference between a. and a. The weight of the ball; we will use the same ball throughout the experiment to ensure that the results are as accurate as possible.
Dependent Variable ------------------ Rate at which the bubbles of oxygen rise, which will be calculated by observing how many bubbles of oxygen rise to the surface of a measuring cylinder (by means of downward displacement) in one minute. This will be measured in bubbles per ten seconds. Control variables: ¨ Volume of substrate used: 100ml ¨ Temperature: taken place at room temperature 21 degrees centigrade ¨ Type of substrate used: Hydrogen peroxide ¨ Mass of meat used: 5g ¨ Amount of water in the test tube in which the oxygen bubbles downward displaces in the water. This is so the time taken for each individual bubble to effectively rise to the bottom of the test tube will take the same amount of time.
All of these ingredients mixed together makes foam by a chemical reaction. The foam “bubble” is filled with oxygen; the yeast is used to remove the oxygen from the hydrogen peroxide. This process is very fast, and that is the reason the foam is formed. During the chemical reaction the bottle or tube starts to get warm. This chemical reaction is called Exothermic Reaction, which means it not only created foam it also created heat. This experiment is done in a long plastic tube. Once the process is occurring it starts to overflow out of the tube and looks like toothpaste. My second experiment is to compare the chemicals, the size of the foam and the reaction time. For the second run the ingredients are: potassium permanganate, 50% hydrogen peroxide, dish soap and water. Potassium permanganate is used for a bigger or larger reaction. It is an inorganic chemical and is a strong oxidizing agent. They are crystals with a bright purple color to them. The color of them is why this experiment eliminated food coloring. The chemical reaction between hydrogen peroxide and the potassium permanganate is very vigorous and it releases steam, but with the water and dish soap mixed in with the two chemicals makes it somewhat bubble and explode into a big tubular
For starters, here is a fun demonstration that you can perform as you explain some of the science of bubbles. Follow the recipe at the end of this article to make some super strong bubbles for your act. Wearing a clown suit is optional.
Independent variables: The temperature of hcl gas will be decreased and increased throughout the experiment.
Baking soda is not only used for cooking and cleaning, but also contains some of the benefits for health. Among them, baking soda is able to relieve heartburn flavor when added to the water and relieve pain caused by exposed to insect bites when applied topically on the skin that are exposed to bites. It is no wonder, if baking soda also has many uses for beauty. In order to save costs and to use natural substances as treatments, try treatment with baking soda to soften the skin, hair, and you still have many other benefits that you can do yourself at home: scrub to smooth skin show off legs and arms free from flecks of black due to dead skin cells have been removed.
The hypothesis was, as the weight of the paper used increases, then the average distance traveled will increase as well. Following the hypothesis the cardstock airplane should have gone farther than the other two. The reasoning being that the cardstock weighed more than the other two. The cardstock weighed 199.6 grams, the construction paper weighed 68.9 grams, and the printer paper weighed 1.8 grams. As stated the independent variables were kinds of paper and the paper types were cardstock, printer paper, and construction paper. What was being measured, also known as the dependent variable, was the average distance traveled in meters. The control group used was the printer paper. The constants were same type of airplane used ( Bulldog Dart ), same person throwing it, same amount of trials for each type of paper ( 3 ), same throwing area, and same start
