$(i)$ $(i)$ $A weak acid;$ $"A weak acid;"$ ........

..........and $(i i)$ $(ii)$ $its conjugate base.$ $"its conjugate base."$

And thus we can write the so-called buffer equation............

$p H = p K_{a} + {log}_{10} {\frac{[A^{-}]}{[H A]}}$ $pH=pK_a+log_10{[[A^-]]/[[HA]]}$

And as we know, when $[A^{-}] = [H A]$ $[A^-]=[HA]$ , $p H = p K_{a}$ $pH=pK_a$ . Do you agree?
