When the lead-acid cell is fully charged, the electrolyte assumes _______ appearance
Correct answer: D. milky
- A. dull
- B. reddish
- C. bright
- D. milky
Explanation
Near full charge, vigorous gassing produces many fine gas bubbles in the electrolyte, giving it a milky appearance. The milky look is therefore associated with the charging process rather than a change to a reddish or bright electrolyte.
