Which one is not an acid salt
  • ✓
    $NaH_2PO_2$
  • B
    $NaH_2PO_3$
  • C
    $NaH_2PO_4$
  • D
    None of these

Answer

Correct option: A.
$NaH_2PO_2$
a
$NaH _2 PO _2$ is not an acidic salt. It is a basic salt. It is a salt of weak acid $H _3 PO _2$ and strong base $NaOH$. Hence, the aqueous solution of $NaH _2 PO _2$ is alkaline in nature.
