p^(I) of H(3)overset(o+)(N)-CH(2)-COOK i...

`p^(I)` of `H_(3)overset(o+)(N)-CH_(2)-COOK` is 5
`H_(3)overset(o+)(N)CH_(2)COOH hArr H_(2)NCH_(2)COO^(-)+H^(+)K_(a)=10^(-4)`
`H_(2)overset(o+)(N)CH_(2)COO^(-)hArr H_(2)NCH_(2)COO^(-)+H^(+)K_(a)=10^(-X)` What is x ?

Text Solution

Verified by Experts

`PI=(1)/(2)(Pka_(1)+Pka_(2)), 5=(1)/(2)(4+Pka_(2)), Pka_(2)=6, ka_(2)=10^(-6), x=6`
