Exactly 1 litre of solution contains 0.018 mole of Ba²+ ions and 0.0018 mole of Pb²* ions. You wish to separate these ions by selective precipitation using the drop-wise addition of a solution of K2SO4. Explain, by using a full calculation, which of the salts BaSO, or PbSO, will precipitate first? Given: Kp (BaSO4) = 1.1 × 10-10 and Ksp (PbSO,) = 1.6 × 10-8

Exactly 1 litre of solution contains 0.018 mole of Ba?+ ions and 0.0018 mole of Pb²+ ions. You wish to separate these ions by selective precipitation using the drop-wise addition of a solution of K2SO4. Explain, by using a full calculation, which of the salts BaSo, or PbSO4 will precipitate first? Given: Kep (BaSO4) = 1.1 x 10-10 and Kẹp (PbSO4) = 1.6 x 10-8 A voltaic cell is set up at 25 °C and delivers 0.060 V. One half cell contains an acidified solution of permanganate and manganese(II) ions, and the other half-cell is based on the following reaction: Br03 (aq) + 6H30*(aq) + 6e Br¯(aq) + 9H20 (f), Eed = 1.44 V
