1.	Assertion (A): Boiling removes both temporary and permanent hardness from water. Reason (R ): Bicarbonates of calcium and magnesium undergoes decomposition on heating
Answer» Both (A) and (R ) are true and (R ) is the CORRECT REASON for (A). Both (A) and (R ) are true but (R ) is not the correct reason for (A) (A) is true but (R ) is false (A) is false but (R ) is true.
