An Investigation into

The Rate of reaction

When Dissolving Sugar

Introduction

I have been asked to perform an investigation on the length of time it takes for a certain amount of sugar to dissolve in a certain amount of water at different temperatures. I will investigate whether the time taken at one temperature and another will be the same, quicker or slower using scientific methods.

Identifying Key Factors

The factors that would affect the dissolving rate are: -

* Volume of water

The larger the volume of water, the quicker the sugar will dissolve because there is more particles for the sugar molecules to collide with.

* Mass of sugar

The more sugar there is the dissolving rate will be slower as there is more molecules to collide with the water particles.

* Size of sugar particles

The bigger they are the slower they will dissolve.

* Temperature

The higher the temperature the quicker the sugar will dissolve

The variable I am going to change is temperature. I will keep all other factors constant to make the experiment fair and so the results are
