Aim To Find the Number of Moles of Water of Crystallisation in Copper (II) Sulphate salt. Introduction Water of crystallisation is the term given to the molecules of water that are used to build up a crystal lattice in some ionic compounds.In copper II sulphate the blue crystals would be impossible without using water molecules to act as ’scaffolding’ within the structure CuSO4.5H2O. When this is heated the water molecules are driven off and the blue crystals become a white powder. As most

Introduction: In this following assignment‚ I will be considering geometric shapes that lead to special numbers. The simplest examples of these are square numbers (1‚ 4‚ 9‚ 16‚ etc)‚ which are derived from squaring 1‚ 2‚ 3‚ and 4. From this I got the equation y= x2. This equation is illustrated in the table below. y=x2 |x |y | |1 |1 | |2 |4 | |3
