Hcl and Na2s2o3

Summary: Investigating the relationship between the concentration of Sodium Thiosulphate and the rate of its reaction between it and Hydrochloric Acid.
Preliminary Work

The computer program was useful as the units and volumes of substances could be changed to judge a means of devising a method: there were two means of which to carry out this experiment. The method chosen was by judging when the cross below the beaker disappears (see Method). However there were a few potential errors to this method (see Evaluation).

Prediction

I predict that the more concentrated the solution of Sodium Thiosulphate the faster the rate of reaction with hydrochloric acid. This is due to the collision theory (see Theory). For example, doubling the concentration of Na2S2O3 from 0.08 mol/dm3 to 0.04mol/dm3 and therefore doubling the rate of reaction.

Theory

The justification for my prediction is the collision theory:

THE COLLISION THEORY

The collision theory is the idea that the more particles there are in a given volume (concentration...
