प्रश्न
Explain, why the following statement is not correct:
Lead chloride can be prepared by adding dilute HCI to lead sulphate solution.
उत्तर
Lead chloride cannot be prepared by adding dilute HCI to lead sulphate solution because lead sulphate is insoluble salt. Infact it can be prepared by adding dilute HCI to lead nitrate solution since lead nitrate is soluble compound.
