Question asked by Filo student

How much will the potential of a hydrogen electrode 71. Consider the cell $\mathrm{Cu}/{\mathrm{Cu}}^{+2}\Vert {\mathrm{Ag}}^{\ast }/\mathrm{Ag}$. If the . change when its solution initially at $\mathrm{pH}=\mathrm{O}$ is concentration of ${\mathrm{Cu}}^{+2}$ and ${\mathrm{Ag}}^{+}$ions becomes ten neutralised to $\mathrm{pH}=7$ ? times then the emf of the cell will :-

1. increases by $0.059\mathrm{V}$ (1) Becomes 10 times
2. decreases by $0.059\mathrm{V}$
3. Remains same
4. increases by $0.41\mathrm{V}$
5. Increases by $0.0295\mathrm{V}$
6. Decreases by $0.0295\mathrm{V}$
