A cell is prepared by dipping copper rod in 1 M copper sulphate solution and zinc rod in 1 M zinc sulphate solution. The standard reduction potential of copper and zin c are `0.34 V and - `0.76 V respectively.
(i) What will be the cell reaction ?
(ii) What will be the standard electromotive force of the cell ?
(iii) Which electrode will be positive ?
