Question

Which pair of reactants can be best used to produce lead (II) sulphate?

Options

• Sulphuric acid + Lead

• Sulphuric acid + Lead hydroxide

• Sodium sulphate + Lead nitrate

• Potassium sulphate + Lead oxide

Answer 1

Sodium sulphate + Lead nitrate

Explanation:

Lead (II) sulphate is an insoluble salt that can only be synthesized from a soluble salt. Lead nitrate is a soluble salt; hence, the optimal reactants for producing lead (II) sulphate are sodium sulfate and lead nitrate.
