The aqueous solution of which of the following salt will have the lowest pH?

Question

The aqueous solution of which of the following salt will have the lowest pH? (A) NaClO 3 (B) NaClO (C) NaClO 4 (D) NaClO 2

Tardigrade Admin · Accepted Answer

NaClO 4, on hydrolysis, gives strongest acid HClO 4 as compared to other salts. This is strongly ionized and gives highest concentration of H +. Therefore aqueous solution of NaClO 4 will have lowest pH value.

Q. The aqueous solution of which of the following salt will have the lowest pH?

$N a Cl O_{3}$

$N a ClO$

$N a Cl O_{4}$

$N a Cl O_{2}$

$N a Cl O_{4}$ , on hydrolysis, gives strongest acid $H Cl O_{4}$ as compared to other salts. This is strongly ionized and gives highest concentration of $H^{+}$ . Therefore aqueous solution of $N a Cl O_{4}$ will have lowest $p H$ value.
