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

Text Solution

Verified by Experts

`k_(a) . k_(b)^(-14) " " :. K_(a) = (10^(-14))/(10^(-10)) = 10^(-4)`
`pH = pka + log. ([x^(-)])/([Hx]) `
` :. pH = 4 + log . 1/1 = 4 " " :. pH = 4`
