Rates of reaction:- sodium thiosulphate + hydrochloric acid

Plan:-

We must produce a piece of coursework investigating the rates of

reaction, and the effect that changing one particular variable has on

the reaction time. The rate of reaction is the time it takes one or

more of the reactants to react or the time it takes to produce a new

product from a chemical reaction. To work out the reaction time we use

the formula.

1 divided by time taken for reaction

There are five factors which affect the rate of a reaction, according

to the collision theory of reacting particles:

1. temperature of solution,

2. concentration of solution,

3. pressure of gases in reaction,

4. surface area of reactants,

5. Catalysts.

For my preliminary experiments I have chosen to investigate the effect

temperature and concentration have on a reaction. I have chosen to

investigate these reactants because the are the most practical for the

lab and equipment that I have available to use also it would take to

much time to prepare a solid in powdered and unpowdered form, and it

is difficult to get accurate readings due to the inevitabilities of

human errors, and as gas is mostly colourless it is difficult to gauge

a reaction changing the pressure, and if a substance is added to give

the gas colour, it may influence the outcome of the experiment.

Similarly the use of a catalyst complicates things, and if used

incorrectly could alter the outcome of the experiment.

My preliminary experiments showed me that it would me more practical

and time saving if I just altered the temperature of the solution as

changing the concentration of the solution was very time consuming.

However the preliminary experiments also helped me to choose a

suitable strength of solution.

Aim:-

To see the effects of a change in temperature on the rate of a

reaction. The reaction that will be used is:

Sodium Thiosulphate + Hydrochloric Acid.

Na2S2O3 (aq) + 2HCl (aq) .

As I decided after my preliminary experiments I will only carry out

one experiment, temperature change whilst all other variables stay

constant. As both, sodium thiosulphate and hydrochloric acid are

soluble in water it means that I would be able to alter the

concentration of either of them. However I have chosen to vary the

sodium thiosulphate as it is available in larger amounts. To alter the

temperature of the solution a water bath will be used to heat up the

acid, thiosulphate and water to the necessary temperature.

I decided on my range temperatures and the concentration that I would

use during my preliminary series of experiments -

I would be using a concentration of 0.

    Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid. The rate of the reaction is the speed that the reaction takes place so by measuring the rate I will measure the amount of time the reaction takes. Hydrochloric acid is a strong acid that is found in digestive juices in the stomach, it is also used for cleaning metals before they are coated. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. When you put calcium carbonate and hydrochloric acid together they react to form calcium chloride, carbon dioxide and water.

  • The Great Gatsby

    1649 Words  | 4 Pages

    Early events from Fitzgerald’s life appear in The Great Gatsby. Fitzgerald resembles Jay Gatsby, a caring man who obsesses over wealth and luxury and falls in love with a beautiful young woman while stationed at a military camp in the South. Nick Carraway, also similar to Fitzgerald, is described as a young man from Minnesota, educated at an Ivy League school (in Nick’s case, Yale), who moves to New York after the war. After the publication of his books, Fitzgerald fell into a life-style of parties, while writing to earn more money to please Zelda by. Gatsby obtains a lot of wealth at a young age, and dedicates his life to earning possessions and throwing parties that he believes will allow Daisy to love him. Fitzgerald, similar to Nick in The Great Gatsby found this new lifestyle thrilling and dramatic, and, like Gatsby, always admired the very rich. In many ways, The Great Gatsby represents Fitzgerald’s explanation of his feelings about the Jazz Age. Fitzgerald was motivated by his love for a woman who symbolized everything he always wanted, even though she led him toward everything he loathed just like Gatsby.

    In the world today, we know that whales are majestic creatures with amazing lifestyles that we don’t completely understand. We also know that however large they are, they are in danger because they have been over hunted and over used by human beings. Today through Commercial Whaling, the whales of the oceans have been put at risk and their population continues to decrease. Countries such as Japan, Iceland, and Norway defy the rules set by The International Whaling Commission under the pretense that they’re whaling for scientific reasons, when in reality they are whaling for commercial reasons of profit. Commercial whaling is a problem in countries around the world, most prominent are the Japanese, and other countries are Iceland and Norway. Over time the status of the whale population has declined because of the increase of technology in whale hunting.

    Francis Scott Key Fitzgerald was on September 24, 1896 and was raised in St. Paul, Minnesota. Though he was an intelligent child, he did poorly in school and was sent to a boarding school in New Jersey in 1911. Despite not being as successful, he managed to enroll at Princeton, for not doing so while attending, he instead he joined the army in 1917, as the first World War neared its end. Meanwhile, his school life wasn't so successful Fitzgerald became a second lieutenant and was stationed in Montgomery, Alabama at Camp Sheridan, meanwhile he was stationed there he met and fell in love with a seventeen-year-old named Zelda Sayre. As a result, with Zelda has an overpowering desire for wealth, fun, and leisure caused their wedding to be delayed until Fitzgerald could prove to be a success. He achieved this by becoming a literary sensation thus earning enough money and fame to convince Zelda to marry him. 1 Fitzgerald's novel The Great Gatsby was said to include many events from Fitzgerald's early life. So the question raised is, did Fitzgerald include himself in The Great Gatsby?

    Because there are more molecules, the frequency of successful collisions is greater, and the reactions happen faster. Safety There are a lot of safety issues we must abide by in this experiment. We must remember that the substances we use in this experiment can be very harmful if used the wrong way. When doing this experiment, it may be necessary to wear safety goggles, as things are very unpredictable, and even though it is very unlikely that the solution will come out of the beaker during the experiment, one must still be cautious of spills. We must make sure that coats and bags are all out of the way while doing the experiment.

    One vital process in the human body observed in chemistry is the idea of chemical kinetics. Chemical kinetics is the study of the rate of reactions, or how fast reactions occur.1 Three factors that affect chemical kinetics are concentration, temperature, and catalysis. As the concentration of a substance increases, the rate of the reaction also increases.1 This relationship is valid because when more of a substance is added in a reaction, it increases the likelihood that the

    To the United Nations, nearly a quarter of children under the age of five are expected to remain underweight in two thousand and fifteen. The World Health Organization has reported hunger and related malnutrition as the greatest single threat to the world's public health. Improving nutrition is widely regarded as the most effective form of aid. Nutrition-specific interventions, which address the immediate causes of under nutrition, have been proven to deliver among the best value for money of all development interventions. In Africa, rates have been increasing for malnourished people (Hanson 204-5). For hundreds of millions of people, starvation is a daily threat. In the poor nations of Africa, Asia, Latin America, billions of hungry people face starvation. It begins with an ache in your stomach that eventually weakens your heart and stops beating. Today about five billion of the world’s five point nine billion live in poor nations. (“Hunger and Malnutrition” web).

    Millions of people die each year, all over the world because of hunger and disease, many of whom are children (Global issues, 2010). Millions of other people suffer because of hunger, many of whom are in Sub-Saharan Africa and Asia. However, there are several thousand tones of food that is wasted every year. This occurs when people through away food, during harvest, during storage and when crop is destroyed by pests, insects, diseases and animals. Food wastage in the poor countries is due to lack of technology and infrastructure and result to as much as quarter of harvest getting lost (Global issues, 2010). According to Global issues (2010), world hunger results from poverty. World hunger is an issue of concern and continuous efforts should be made in order to save millions of people around the world. Solving the real cause of poverty is crucial towards permanently solving the world hunger problem.
