Question 343Electricity/Electronics - Assistant Engineer70% to pass
Which of the following activities occurs during the charging process of a lead-acid storage battery?
AI Explanation
The correct answer is B) The specific gravity of the acid increases.
During the charging process of a lead-acid storage battery, the chemical reactions cause the specific gravity of the electrolyte (sulfuric acid) to increase. As the battery charges, the lead sulfate on the plates is converted back to lead and lead dioxide, releasing sulfuric acid back into the electrolyte, which increases its specific gravity.
The other answer choices are incorrect because: A) Hydrogen gas is produced, not absorbed, during the charging process. C) Oxygen gas is produced, not absorbed. D) Both plates change chemically to lead and lead dioxide, not lead sulfate, during charging.
