(b,c,d) Let BA be this salt BA → B + + A –

A – does not undergo hydrolysis because HA is strong acid. B + undergoes hydroysis

h = h = degree of hydrolysis where K h = Hydrolysis constant = .

h ∝ greater the hydrolysis constant greater the h(degree of hydrolysis).

h ∝ greater the K b lesser the h.

Hydrolysis is endothermic, K h increases with temperature and h also increase with temperature.

h ∝ V = volume of salt solution hence h increases with dilution. K h =

Both K w and K b change with temperature, hence K h changes with temperature.

Hence, statement(b) is correct. h increases if K b decreases, statement(c) correct.

It is found that as temperature increase, K w and K b increase but increase in K w is greater than increase in K b .

Hence, h increases with increase in temperature. or h decrease in temperature., hence statement.

is correct.

is not correct from explanation of .
