Question

Which of the following component is formed
on the positive plate after the discharged
reaction in a lead-acid battery?
Sulphuric acid
Lead sulphate
Spongy lead
Lead peroxide​

Answer 1

Answer:

In the fully charged state, the negative plate consists of lead, and the positive plate is lead dioxide. The electrolyte solution has a higher concentration of aqueous sulfuric acid, which stores most of the chemical energy.

Answer 2

LEAD SULPHATE is formed on the positive plate after the discharged reaction in a lead-acid battery.

LEAD-ACID BATTERY -

• The batteries generate electric current via chemical reactions.
• The current generated is extracted from the lead-acid battery by discharging process.
• The discharging cell forms a galvanic cell with a negative plate made of lead and a positive plate of lead oxide in the charged state.
• During recharging the chemical reaction involved is represented as -
