Question

Lead Sulfate is formed in the negative plate of a VRLA battery during (a) Charging (b) discharging(c) charging and discharging

Answer 1

Answer:

A full discharge causes strain and each discharge/charge ... and causes a buildup of sulfation on the negative plate.

Answer 2

Answer:

The Answer is:

The negative plate in a lead acid cell consists of a lead alloy lattice or grid in which the spaces of the grid are filled with chemically-active lead sponge. If a fully charged negative plate is removed from the acid and exposed to the air it will heat up rapidly, produce steam from the water on the surface and quickly form a deposit on the surface. During this chemical reaction, oxygen from the air reacts with the lead to produce lead oxide (PbO) and heat.
