positively charged (02 marks) (d) (i) Polarization is the formation of hydrogen gas at the positive electrode . The hydrogen bubbles insulate the positive electrode from the electrolyte and this increases the internal resistance of the simple cell, (ii) Polarization in a simple cell can be minimized by (01 mark) introducing a depolarizing agent like manganese (iv) oxide that oxidizes the hydrogen to water. (03 marks) (e) is the ammeter reading. QUESTION 7
