A certain buffer solution contains equal concentrations of $X^{-}$ and $H X$ . The $K_{b}$ for $X^{-}$ is $1 0^{- 10}$ . The $P^{H}$ of the buffer is

Answer:

Solution:

$K_{b}$ of $X^{-} = 1 0^{- 10}$

Ka of HX IS $1 0^{- 4}$

For an acidic buffer

$[H^{+}] = K a [\frac{acid}{salt}] = K a = 1 0^{- 4}$

$P^{H} = 4$
