A weak acid `HA` and a weak base `BOH` are having same value of dissociation constants . If `pH` of `0.01M HA` is 4, then `pH` of `0.01 M BOH` will be

The dissociation constant of an acid, HA is 1 x 10^-5 The pH of 0.1 M solution of the acid will be

For a weak acid HA with dissociation constant 10^(-9) , pOH of its 0.1 M solution is

A 0.1 M solution of a weak acid HA is 1% dissociated. The approximate value of dissociation constant is :

At 25^(@) C dissociation constants of acid HA and base BOH in aqueous solution are same. The pH of 0.01 M solution of HA is 5. The pOH of 10^(-4) M solution of BOH at the same temperature is :

At 25^(@) C dissociation constants of acid HA and base BOH in aqueous solution are same. The pH of 0.01 M solution of HA is 5. The pOH of 10^(-4) M solution of BOH at the same temperature is :

At 25^(@) C dissociation constants of acid HA and base BOH in aqueous solution are same. The pH of 0.01 M solution of HA is 5. The pOH of 10^(-4) M solution of BOH at the same temperature is :

The pK_a of a weak acid HA and pk_b of a weak base BOH are 4.60 and 4.80 respectively. The pH of 0.1 M solution of the salt, BA, formed from the acid HA and base BOH is
