Explanation:
milli equivalent of \(\mathrm{H}^{+}\)ion \(=\mathrm{N} \times \mathrm{V}\) \( =M \times v . f \times V \) \( =0.05 \times 2 \times 10=1 \) milli equivalent of \(\mathrm{OH}^{-}=0.1 \times 10=1\) milli equivalent of \(\mathrm{H}^{+}=\)milli equivalent of \(\mathrm{OH}^{-}\) \( \therefore \mathrm{pH}=7 \)
