HA is a weak acid and BOH is a weak base. For which of the following salts the extent of hydrolysis is independent on the concentration of the salt in its aqueous solution

Question

HA is a weak acid and BOH is a weak base. For which of the following salts the extent of hydrolysis is independent on the concentration of the salt in its aqueous solution (A) NaA (B) NaB (C) BCl (D) BA

Tardigrade Admin · Accepted Answer

The extent of the hydrolysis (h) of the salt made by weak acid and weak base is independent on the concentration of the salt h=(√Kh/√Kh + 1) Kh=hydrolytic constant=(Kw/Ka Kb)

Q. HA is a weak acid and BOH is a weak base. For which of the following salts the extent of hydrolysis is independent on the concentration of the salt in its aqueous solution

NaA

NaB

BCl

BA

The extent of the hydrolysis (h) of the salt made by weak acid and weak base is independent on the concentration of the salt

$h = \frac{K _{h}}{K _{h} + 1}$

$K_{h} = h y d ro l y t i c co n s t an t = \frac{K _{w}}{K _{a} K _{b}}$

The extent of the hydrolysis (h) of the salt made by weak acid and weak base is independent on the concentration of the salt h=Kh​+1​Kh​​​ Kh​=hydrolyticconstant=Ka​Kb​Kw​​

The extent of the hydrolysis (h) of the salt made by weak acid and weak base is independent on the concentration of the salt

$h = \frac{K _{h}}{K _{h} + 1}$

$K_{h} = h y d ro l y t i c co n s t an t = \frac{K _{w}}{K _{a} K _{b}}$
