Q$)$ Calculate whether cu will corrode in dearated cuSou $PH=0$ to form $C{u}^{+2}($activity $=0\mathrm{.}1)$ and $H_2(1$atm$)$ what is the cerrosion tendency in volts.

Q$/$ Similarly Calculation werther cu will Corrode in dearated $)=(0\mathrm{.}5$ assuming the $Cu(C{N}^{-}{)}_2$ is formed. The activity of which ${10}^{-4}$

$cn(CN{)}_2+e2x{N}^{-}+cu,E=-0\mathrm{.}44v$
