Question

Which one of these is not an acid salt ? (A) NaH2PO2 (B) NaH2PO3 (C) Na2H2S2O7 (D) NaH2PO4

Tardigrade Admin · Accepted Answer

H3PO4 is tribasic. So NaH2PO4 is acidic salt. H3PO2 is monobasic. Hence NaH2PO2 is not an acidic salt. It is a neutral salt. NaH2PO3 and Na2H2S2O7 are also acidic salts.

Q. Which one of these is not an acid salt ?

$N a H_{2} P O_{2}$

$N a H_{2} P O_{3}$

$N a_{2} H_{2} S_{2} O_{7}$

$N a H_{2} P O_{4}$

$H_{3} P O_{4}$ is tribasic. So $N a H_{2} P O_{4}$ is acidic salt. $H_{3} P O_{2}$ is monobasic. Hence $N a H_{2} P O_{2}$ is not an acidic salt. It is a neutral salt. $N a H_{2} P O_{3}$ and $N a_{2} H_{2} S_{2} O_{7}$ are also acidic salts.
