Question : Which acid makes the atmosphere of Venus have thick white and yellowish clouds?
Option 1: Sulphuric acid
Option 2: Nitric acid
Option 3: Acetic acid
Option 4: Hydrochloric acid
Correct Answer: Sulphuric acid
Solution : The correct answer is Sulphuric acid.
Venus is entirely covered in dense clouds of sulphuric acid, and its atmosphere is composed of carbon dioxide. The cause of these contradictory circumstances is Venus's runaway greenhouse effect. Another name for Venus is the Morning or Evening Star. Because Venus rotates in reverse, the Sun rises in the west and sets in the east on this planet.
