    An Investigation into Electrolysis - Copper Sulphate Introduction Decomposition caused by electricity is called electrolysis. The electrical energy causes a chemical change. When a salt is dissolved in water, its ions become free to move so the solution can be "electrolyzed." The products of the electrolysis depend on the chemical solution, its strength and the type of electrode. The cathode is negatively charged and therefore attracts to it positive ions. E.g. hydrogen. The more reactive

    Investigation to Identify the Formula of Hydrated Copper Sulphate Aim: I plan to investigate the formula of Hydrated Copper Sulphate and, more importantly, what x stands for in the formula (CuSO4.xH2O). This will tell me how many molecules of water surround each molecule of Copper Sulphate. To do this I plan to work out the amount of water a set mass of Hydrated Copper Sulphate loses when it becomes anhydrous. I will work this out by measuring the difference in mass between the two states

    Electrolysis of Copper in Copper Sulphate Solution Introduction Aim This is an investigation into how temperature affects the amount of copper lost from the Anode and gained on the Cathode during electrolysis. Electrolysis is… The chemical change by passing electric charge through certain conducting liquids (electrolytes). The current is conducted by migration of ions - negative ones from the Anode (positive electrode), and positive ones to the Cathode (negative electrode).
