Which one of the following will increase...

Which one of the following will increase the voltage of the cell ? `(T = 298 K)`
` Sn+ 2Ag^+ rarr Sn^(2+) +2 Ag`.

A

increases in the size of silver rod

B

increases in the concentration of `Sn^(+2)` ions

C

increases in the concentration of `Ag^(+)` ions

D

none of the above

Text Solution

Verified by Experts

The correct Answer is:
C
Due to reduction of `Ag^(+)`
`Ag^(+)+e^(-)rarr Ag : Ag` will deposit on cathode
Ag rod will increase in size.
