Vedclass · Answer

(A) An acid salt is a salt that contains at least one replaceable hydrogen atom attached to an electronegative atom like oxygen. In $NaH_2PO_2$ (sodium hypophosphite),the structure is $Na[H_2PO_2]$,where both hydrogen atoms are directly bonded to the phosphorus atom ($P-H$ bonds). Since these hydrogen atoms are not bonded to oxygen,they are not acidic and cannot be replaced by a base. Therefore,$NaH_2PO_2$ is not an acid salt.
