Is it possible to store copper sulfate solution in a gold vessel?
We can store CuSO4 solution in a gold vessel if the following redox reaction occur 2Au + 3Cu2+ → 2Au3+ + 3Cu The cell corresponding to the above redox reaction may be represented as: Au / Au3+ || Cu2+ / Cu and E°cell = E°Cu2+ , Cu E°Au3+ Au = 0.34 – 1.50 = 1.16 v since the EMF of the above cell reaction is – ve, therefore, CuSO4 solution does not react with gold in other words, the CuSO4 solution can be stored in a gold vessel
