The dissociation constant of water is `1 xx 10^(-14) mol ^(-2) litre ^(-2)`. What is the pH of 0.001 M KOH soluiton ?

Given that the dissociation constant for H_2O , K_w=1xx10^-14 mol^2 by litre square, the pH of a 0.001 M KOH solution will be

The dissociation constant of aniline, C_6H_5NH_2 is 4.3 xx 10^(-10) mol L^(-1) . Calculate the pH of a 0.01 M solution of aniline in water.
