The thick and yellowish clouds of Venus are primarily composed of droplets of Sulphuric acid.
– The atmosphere of Venus is extremely dense and hot.
– While the main atmospheric gas is carbon dioxide, the visible cloud decks are made of sulfuric acid.
– These clouds contribute significantly to Venus’s high reflectivity (albedo).
The sulfuric acid in Venus’s atmosphere is believed to form from the photochemistry of water, sulfur dioxide, and carbon dioxide. The lower atmosphere contains trace amounts of water vapor and sulfur dioxide, which are thought to fuel the formation of these clouds.
