Which best describes a lead-acid cell when its electrodes are coated with PbSO4?

Question

a Charged
b Short circuit
c Discharged
d Parallel circuit

Answer 1

Each cell contains (in the charged state) electrodes of lead metal (Pb) and lead (IV) oxide (PbO2) in an electrolyte of about 37% (5.99 Molar) w/w sulfuric acid (H2SO4). In the discharged state both electrodes turn into lead(II) sulfate (PbSO4) and the electrolyte loses its dissolved sulfuric acid and becomes primarily water. Due to the freezing-point depression of water, as the battery discharges and the concentration of sulfuric acid decreases, the electrolyte is more likely to freeze.

Here, as the electrodes are coated with PbSO4 ,it means the cell is in Discharged State.
Hence, option 'C' is correct.

Answer 2

Of the choices given, c is the best. If I remember my battery chemistry correctly, the correct term is unchargeable.

Answer 3

c

Answer 4

c Discharged
good luck....

Answer 5

c) discharged
