Write the equation for the laboratory preparation of: (i) Sodium sulphate using dilute sulphuric acid. (ii) Lead sulphate using dilute sulphuric acid.
Give reason for the following :
(a) Though lead is above hydrogen in the activity series, it does not react with dilute hydrochloric acid or dilute sulphuric acid.
(b) Potassium and sodium are not used fro reaction with dilute hydrochloric acid or dilute sulphuric acid in laboratory preparation of hydrogen.
Sodium sulfate using sulphuric acid.
