The standard EMFfor the given cell reaction Zn+Cu^(2+)toCu+Zn^(2+) is 1.10V at 25^(@)C. The EMF for the cell reaction, when 0.1M Cu^(2+) and 0.1M" "Zn^(2+) solution are sued, at 25^(@)C is

Answer»

1.10V
0.110V
`-1.10V`
`-0.110V`

Solution :`E_(cell)=(E_(cell)^(o)-(0.059)/(2)"LOG"((ZN^(++)))/(CU^(++)))`
`=1.10-(0.059)/(2)"log"(0.1)/(0.1)=1.10V`
