What are the compounds that contribute to the formation of acid rain?

Answer 1

Sulphur-di-oxide (SO2), NO2, NO3, react with the water molecules in the atmosphere to produce acids. Nitrogen oxides can also be produced naturally by lightningstrikes and sulfur dioxide is produced by volcanic eruptions. The chemicals in acid rain can cause paint to peel,corrosion of steel structures such as bridges, and erosion of stone statues.

"Acid rain" is a popular term referring to the deposition of wet (rain, snow, sleet, fog, cloud water, and dew) and dry (acidifying particles and gases) acidic components. Distilled water, once carbon dioxide is removed, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are alkaline. "Clean" or unpolluted rain has an acidic pH, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid. However, unpolluted rain can also contain other chemicals which affect its pH. A common example is nitric acid produced by electric discharge in the atmosphere such as lightning.[1] Carbonic acid is formed by the reactionH2O (l) + CO2 (g) H2CO3 (aq)

Carbonic acid then can ionize in water forming low concentrations of hydronium and carbonate ions:H2O (l) + H2CO3 (aq) HCO3− (aq) + H3O+ (aq)

Acid deposition as an environmental issue would include additional acids to H2CO3.

Answer 2

Sulphur dioxide and Nitrous oxide reacts in the air to produce acid rain. These to gaseous substances produce acid rain

Answer 3

Carbon dioxide is produced.

Answer 4

suphate and nitrates mixed with water causes acid rain

Answer 5

Many gases like SO2, CO2 which form H2SO4 and H2CO3 respectively

Answer 6

Sulphur and oxygen

Answer 7

Sulphur dioxide and Nitrogen oxides

Answer 8

Sulphuric acid.
