Relation between Ka and Kb -

K_{a}\times K_{b}=K_{W}

or\:P(K_{a})+P(K_{b})=P(K_{W})=14   (at\:298K)

- wherein

K_{a}=dissociation \:constant\:of\:acid

K_{b}=dissociation \:constant\:of\:base

K_{W}=ionic \:product\:of\:water

 

 .01 mole of NaOH will be completely neutralised by .01 mole of HCl. Hence remaining part of NaOH is .09 mole. as equal volume is mixed [OH-]=.04514

P(H) = 14- P(OH) = 14-log [OH-] =12.65
