QUESTION 4 The minerals of a 50.0 kg ore sample from a South African mine in Northwest were dissolved by acid leaching to make up a solution whose volume was 25.0 dm³. When this solution was analysed it was found to contain 0.200 mol.dm-³ of Cd²+ (aq) ions and 0.150 mol.dm-³ of Ni²+ (aq) ions. The solution was then subjected to electrolysis at 25.0°C. Calculate the mass percentage purity of the metal that plated last.
