Preliminary work Before doing our main experiment, we will have to conduct another experiment, to see what concentration of acid we will have to use.
Conclusion From my graph I can see that the time taken for the magnesium to disappear decreases as the volume of hydrochloric acid increases.
This 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.
Chemistry 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 reaction rate will tell me how fast or slow a chemical reaction is and there are four things that could Investigating the effect of varying concentration on the reaction between magnesium ribbon and hydrochloric acid Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid.
This is because for the Rates of Reaction - Sodium Thiosulphate and Hydrochloric acid In this piece of coursework, I will study how concentration affects the rate of reaction.
I will do so by timing the reaction of Sodium Thiosulphate with an acid.(Because there will be more collisions between sodium thiosulphate and hydrochloric acid.)Describe how you will ensure your results are as accurate, reliable and precise as possible increase the concentration of the Hydrochloric acid, the frequency of collisions increased so the rate of reaction also increased.This is because the higher the concentration of Hydrochloric acid the more frequent the collisions will be between the Magnesium strip and Hydrochloric acid particles.We could get the right amount of results of this, so we then tested the other extreme - the lowest molarity. Chemistry coursework: An investigation of the affect of the concentration an of the rate of reaction. We are trying to find out the affect of acid concentration on the rate of reaction, we are using 2, 1.5, 1, 0.5, 0.25 Molar acid.In our experiment, we are reacting it with sodium thiosulphate.Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas.One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction.This means a lot of productive collisions between reactants.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.If I had a wide range of molarities, it would be easy to see this pattern.METHOD Before conducting our experiment where we would get our facts and evidence from, we carried out a pre-test.
