Rate of Reaction - Sodium Thiosulphate and Hydrochloric Acid


Aim

Investigation, to find out how the rate of reaction between Sodium
Thiosulphate and Hydrochloric acid is affected by changing the
concentration.

Introduction

I must produce a piece of coursework investigating the rate of
reaction, and the effect different changes have on them. The rate of
reaction is the rate of loss of a reactant or the rate of development
of a product during a chemical reaction. It is measured by dividing 1
by the time taken for the reaction to take place. There is five
factors which affect the rate of a reaction, according to the
collision theory of reacting particles: temperature, concentration (of
solution), pressure (in gases), surface area (of solid reactants), and
catalysts. I have chosen to investigate the effect of concentration on
the rate reaction. This is because it is the most practical to
investigate. Dealing with temperatures is a difficult task especially......
