Chemistry Coursework An investigation to find out how changing the concentration of Sodium Thiosulphate affects its rate of reaction with Hydrochloric acid. Section 1 - Planning In this experiment I am going to find out how the rate of reaction between sodium thiosulphate and dilute hydrochloric acid is affected by changing the concentration of both substances. The equation to this is as follows: Na2S2O3 (aq) + 2HCl (aq) = 2NaCl (aq) + H2o (l) + 5O2 (g) + S (s) + H2o (l) P2a Safety There are a lot of safety issues we must abide by in this experiment also. We must remember that the substances, which we use in this experiment, can be very harmful if used the wrong way. When we do 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 would come out of the conical flask during the experiment,...
