Question

To a one litre solution containing 8 grams of sodium hydroxide, 14.7 grams of sulphuric acid is added. p^H of the solution at 298 K is

Moderate

Solution

Number of gram equivalents of base = 8/40 = 0.2
Number of gram equivalents of acid = 14.7/49 = 0.3
Nature of resultant solution is acidic
Number of gram equivalents of acid left = (0.3 - 0.2)
$\begin{matrix} ∴ [H^{+}] = 0 .1 \times \frac{1}{1} \\ [H^{+}] = 0 .1 M \\ p^{H} = 1 \end{matrix}$
