How the rate of reaction changes in a reaction between Hydrochloric Acid and Sodium Thiosulphate

Chemistry coursework: An investigation of the affect of the concentration an of the rate of reaction. Introduction. 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. 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 lower the …showed first 75 words of 1309 total…

I think that we could have made the experiment better by using the same x on the piece of paper and using the exact same conical flask, all looking at the chemicals in the same place and distance away and to keep really hard to the variables table we drew up instead of stupidly missing points.
