1.	Which of the following will act as cathode and anode respectively in a dry-cell battery?(a) Zinc and carbon(b) Carbon and zinc(c) Magnesium and zinc(d) Zinc and ammonium chlorideThe question was asked in an interview for internship.I would like to ask this question from Eight Forms topic in section Eight Forms of Corrosion of Corrosion Engineering
Answer» Correct choice is (B) CARBON and zinc For EXPLANATION: Battery is a combination of cells in which chemical energy is converted into electrical energy. Carbon (noble electrode) ACTS as cathode and zinc (active electrode) acts as an anode. Moist ammonium chloride is used as an electrolyte.
