The electrochemical cell shown below is a concentration cell. M|M^(2+)( saturated solution of sparingly soluble salt, MX_(2))||M^(2+)(0.001 mol dm^(-3))|M The emf of the cell depends on the difference in the concentration of M^(2+) ions at the two electrodes. The emf of the cell at 298 is 0.059V . The solubility product (K_(sp),mol^(3) dm^(-9)) of MX_(2) at 298 based on the information available the given concentration cell is ( Take 2.303xxRxx298//F=0.059V)
