1.	Assertion (A): Boiling removes both temporary and permanent hardness from water. Reason (R ): Bicarbonates of calcium and magnesium undergoes decomposition on heatingA. Both (A) and (R ) are true and (R ) is the correct reason for (A).B. Both (A) and (R ) are true but (R ) is not the correct reason for (A)C. (A) is true but (R ) is falseD. (A) is false but (R ) is true.
Answer» Correct Answer - D Boiling removes only temporary hardness because soluble bicarbonates of calcium and magnesium undergo decomposition on heating and insoluble carbonates are formed.
