describe the electrochemistry involved in each battery.(a) Leclanche dry cell (b) button battery (c) fuel cells) (d)lead storage battery

1. Briefly define the following terms. (a) Anode and cathode (b) Reference electrode (c) Standard Hydrogen Electrode (SHE) (d) Reduction potentials (e) Salt bridge

When a solution of NaI in water was electrolyzed with graphite electrodes, a gas was evolved at the cathode and a yellow-brown color was observed around the anode. The solution became basic. Which one of statements (a) - (d) is not correct? If all are correct, select option (e). Please see the data page for relevant electrode potentials for the half reactions.a) OH- ions were formed at the cathode.b) I- ions were oxidizedc) The gas, which was evolved, was O2.d) Water was reducede) Statements (a) - (d) are all correct
