Final answer:
The technical name for H2SO4 and H2SO3 falling from the sky in the liquid form as rain, sleet, or snow is acidic precipitation.
Step-by-step explanation:
The technical name for H2SO4 and H2SO3 falling from the sky in the liquid form as rain, sleet, or snow is acidic precipitation. Acid rain is a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. It occurs when sulfur dioxide and nitrogen oxides react in the atmosphere with water, oxygen, and other chemicals to form various acidic compounds, resulting in a mild solution of sulfuric acid and nitric acid.
