An Investigation Into The Rate Of The Reaction Between Dilute Hydrochloric Acid And Sodium Thiosulphate Plan Aim The aim of this investigation is to investigate the effect of changes in concentration of the sodium thiosulphate on the rate of the reaction between dilute hydrochloric acid and sodium thiosulphate. Variables There are four main variables that affect experiments such as this. They are: * The Temperature Of The Reaction Reactions get faster as the temperature is increased. As a rough approximation, a 10ºC increase in temperature doubles the rate of a reaction. There are two factors at work here. 1) Increasing the temperature means that the particles are moving faster and so collide with each other more often. That will make the reaction go faster, but it only accounts for a small part of the increase in rate. 2) Not all collisions end up in a reaction. Many particles just bounce of each other. In order for anything interesting...
