You are given a mixture of precipitated copper hydroxide and zinc hydroxide. Name a solvent which will dissolve:
Both copper hydroxide and zinc hydroxide
Sodium hydroxide solution can be used to distinguish between i. iron (II) sulphate solution and (ii) iron (III) sulphate solution; because these solutions give different coloured precipitates with sodium hydroxide solution. Give the colour of the precipitate formed with each of the solution.
