Consider the dissociation equilibrium of the following weak acid
\(\mathrm{HA} \rightleftharpoons \mathrm{H}^{+}(\mathrm{aq})+\mathrm{A}^{-}(\mathrm{aq})\)
If the pKa of the acid is 4 , then the pH of 10 mM HA solution is $\_\_\_\_$ .(Nearest integer)
[Given: The degree of dissociation can be neglected with respect to unity]
