A certain buffer solution contains equal concentration of `X^(-)` and HX. `K_(b)`, for `X^(-)` is `10^(-10)`. Find the pH of buffer.

Text Solution

Verified by Experts

The correct Answer is:
4
` K_b =10 ^(-10 ) , Ka = 10 ^(-4) [X^(-) ]=[HX]`
` pH= P^(Ka) +log ""([X^(-)])/([HX]) =-log 10 ^(-4) =4`
