RATES OF REACTION COURSEWORK HYDROCHLORIC ACID AND CALCIUM CARBONATE

I know from my knowledge of science, that by adding together a carbonate and an acid, that a salt, water and Carbon Dioxide are produced. We have decided to test different concentrations of hydrochloric acid for our experiment because it will give us sufficient results to make our evidence reliable. In my evaluation I will comment on how reliable my results were and how. We could get the right amount of results of this, so we then tested the other extreme – the lowest molarity. When calcium carbonate is added to hydrochloric acid a reaction takes place. I am going to measure 50cm3 hydrochloric acid, add it to 1g of calcium carbonate then time the reaction rate.

The collision theory will be involved in this, for instance the more concentrated the acid we use, the faster the reaction will occur and the. As time goes on these reactants will become less and less because reactants have been turned into products , therefore less collisions, so the rate of reaction will slow down. Before conducting our experiment where we would get our facts and evidence from, we carried out a pre-test. Preliminary workBefore doing our main experiment, we will have to conduct another experiment, to see what concentration of acid we will have to use. It can also highlight some of the problems they are going to find with the real experiment, e.

If the solution is made more concentrated, there will be more particles in the solution. The faster the gas is made, the faster the reaction is going. Sodium Thiosulphate Investigation Essay. The reaction we are going to study is: The concentration of Sodium Thiosulphate will be changed throughout the investigation and this makes it the independent variable in my investigation. Investigation Experiment to investigate factors affecting the rate of reaction between magnesium ribbon and hydrochloric acid.

All the atoms in a water molecule have a full outer shell, so they. Preliminary workBefore doing our main experiment, we will have to conduct another experiment, to see what concentration of acid we will have to use. In this coursework, I will include background knowledge, prediction, safety, results, calculations, graphs, coufsework analysis, conclusion and an evaluation. If I had a wide range of molarities, it would be easy to see this pattern. It could count as preliminary work if discussed and written up as such.

In our experiment, we are reacting it with sodium thiosulphate. This is because for the. In the reaction between hydrochloric acid and magnesium.

Chemistry Rate of Reaction Coursework for Calcium Carbonate and Hydrochloric Acid

This reaction rate will tell me how fast or slow a chemical reaction is and there are four things that could. The Reaction Between Marble Chips and Hydrochloric Acid words – 3 pages Using the syringe method I am going to investigate the reaction between Marble chips and hydrochloric acid by measuring the volume of carbon dioxide formed. This makes collisions between important molecules more likely and xoursework collide more often. We did 4 experiments to find out how the rate of reaction changes with differing concentrations of Sodium Thiosulphate, Hydrochloric Acid and water.

Rate Of Reaction Between Hydrochloric Acid And Calcium Carbonate – Essay – Words – BrightKite

IntroductionIn the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. Free school trial Try all our Yenka products free for 15 days in school. Reaction Rate Between Magnesium Ribbon And Hydrochloric Acid words – 9 pages AimIt is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid.

The pre-test helped us decide the exact details of our experiment. Exploring Factors That Affect the Rate of a Chemical Reaction Involving Magnesium and Hydrochloric Acid words – 6 pages increase the concentration of the Hydrochloric acid, the frequency of collisions increased so the rate of reaction also increased.

Experiment to investigate factors affecting the cuorsework of reaction between magnesium ribbon and hydrochloric acid words – 9 reactipn Experiment to investigate factors affecting the rate of reaction between magnesium kf and hydrochloric acid Rates of Reaction: I know from my knowledge of science, that by adding together a carbonate and an acid, that a salt, water and Carbon Dioxide are produced.

Task 2 is not suitable for Standard Grade Scotland. I will need 50cm3 of hydrochloric acid, 50cm3 of water, 1g of calcium carbonate, beaker, measuring cylinder, stop watch and weighing scales. We could get the right amount of results of this, so we then tested the other extreme – the lowest molarity.

At the beginning of the reaction, there are lots of reactants particles and no products. Investigating Reaction Rates of Sodium Thiosulphate and Hydrochloric Acid words – 9 pages middle of the investigation then the rate of reaction will be affected.

I think that during our experiment, the cslcium the molarity of acid the quicker the rate of reaction will be, I think this because of the collision theory. It can also highlight some of the problems they are going to find with the real acir, e.
