Introduction

The aim of this investigation is to show how the concentration of a solution will affect the rate of a reaction. This will be proved by testing eight different concentrations; each being tested three times. The theory will be proved by the speed of which the reaction takes place and drawing a conclusion on whether an increased concentration, increases a reaction.

Variables

From preliminary experiments and personal investigation there are a number of variables that were possible to choose before coming to my chose one. The other possible variables are:

Temperature

The temperature of the solution affects the rate because as the temperature increases so does the movement of particles as they gain higher amounts of energy which means that there is an increased probability of particles coliding. This means that...
