If the $pKa$ of lactic acid is $5$,then the $pH$ of $0.005 \ M$ calcium lactate solution at $25^{\circ} \ C$ is $........ \times 10^{-1}$ (Nearest integer). The structure of lactic acid is given below:

Calculate the $pH$ on mixing $100 \ mL$ of $0.2 \ M \ HCN$ with $400 \ mL$ of $0.05 \ M \ KOH$ at $25 \ ^\circ C$ ($pK_b$ for $CN^- = 8$).
