Acid rain was an environmental hyperbole covering the effect of sulfur dioxide and nitrogen dioxide gasses being washed out of the atmosphere by rainfall. Downstream from coal-fired power generation and metal reduction processes, these gasses were part of the gas stack chemistry; sourced as minor constituents of the process coal.
