For a galvanic cell, the cell notation is

Zn\left( s \right)/Z{n^{ + 2}}\left( x \right)//C{l^ - }\left( y \right)/C{l_{2\left( {1\,\,atm} \right)}},pt

To produce highest EMF, the values of x and y should be

View answer and explanation

Correct option: B

x-0.01M,y- 0.01M

Option C (x-0.01M,y-1M) is correct because a lower concentration of

Zn^{2+}

and a higher concentration of

Cl^-

will maximize the EMF.
