Show that, `pK_a+pK_b=pK_b` where `K_b` and `K_a` are the ionisation constants of weak base (B) and its conjugate acid. `(BH^+)` respectively.

The pH of a buffer solution obtained by the combination of a weak base (B) and its conjugate acid (BH^+) is 9. If the concentrations of B and BH^+ in the buffer are 0.2(M) and 0.02(M) respectively, then find the ionisation constant of the weak base.

prove that E(ax+b)=aE(x)+b where a and b are constants

Show that, degree of dissociation of a weak monobasic acid, alpha=(1)/(1+10^((pK_(a)-pH))), where, K_(a) is the dissociation constant of the weak acid at experimental temperature.

At 25^(@)C , the ionisation constant (K_(a)) of weak acid HA is 10^(-6) . What will the value of ionisationn constant (K_(b)) of its conjugate base (A^(-)) be at that temperature ?

A weak tribasic acid, H_(3)A , in its aquous solution ionises in the following step: If the ionisation constants of the steps are K_(1),K_(2) and K_(3) respectively, then determine the overall ionisation constant of H_(3)A . H_(2)A^(-)(aq)+H_(2)O(l)hArrH_(3)O^(+)(aq)+HA^(2-)(aq).
