and Processing Raw data Table of raw data Qualitative observation: At the start of the experiment‚ the crystals were blue. During the heating‚ the crystals turned white which means that they lost their water molecules. The source of hydrated copper sulphate consists of both small grains and large grains of the salt. Therefore during the heating process‚ the smaller grains of the hydrated salt turned from blue to white in just 1 minute. In other words‚ there is an uneven heat distribution‚ which
