(a) Explain why alkaline batteries always contain a separator between the anode and the cathode material, and describe the properties that separator materials must have, giving reasons. (b) Consider a Daniell cell that includes Cu and Zn electrodes and electrolytes CuSO4 and ZnSO4. Given the standard electrode potentials are ECu0=+0.34(V),EZn0=0.76(V) (i) Write down the reaction on the copper electrode (ii) Calculate the potential at the copper electrode for 0.1 mol/L and 0.5mol/L (iv) Calculate the potential between the copper and the zinc electrodes immersed in electrolytes containing 0.1mol CuSO4 and 0.5molZnSO4 (v) In the case of (iv), what is the cell potential
