What is Acid Rain?

Acid rain is the name given to rain, snow or sleet contaminated with acid substance so that its acidity is greater than the limit expected by normal concentrations of carbon dioxide dissolving in the rain to given carbonic acid. The increase acidity is caused by larger concentrations of a number of contaminates, principally the strong acids, nitric and sulphuric, which arise from industrial effluents containing oxides of nitrogen and sulphur.

It can mark fruit and leaves, and adversely affect soil but its main effect is on aquatic ecosystem especially in regions which cannot naturally buffer acidic inputs such as those with thin soils and granite rocks.

    Just recalled this topic from chemistry learnt years ago. Like it leading to rusting etc. Would’ve loved more details on this topic.
