The standard oxidation potential of $Ni/N{i}^{+2}$  electrode is $0.236V$  if this combined with hydrogen electrode in acid solution. At what  $pH$ of the solution the measured emf will be zero at  ${25}^{0}C$ and 1 atm pressure  $(\text{assuming}\left(N{i}^{+2}\right)=1M,\frac{2.303RT}{F}=0.059)$ (Round off to nearest integer)
