Calculate the minimum mass of NaOH required to be added in R.H.S. to consume all the

\text{H}^+

present in R.H.S. of cell of emf +0.701V at 25°C before its use. Also report the emf of cell after addition of NaOH.

\text{Zn} | \text{Zn}^{2+} (0.1\text{M}) || \text{HCl} (1 \text{ litre}) | \text{Pt}_{\text{H}_2}(\text{g}) (1 \text{ atm})

E_{\text{Zn}^{2+}/\text{Zn}}^\circ = +0.760\text{V}
