When was the first
acid rainstorm? The first recorded acid rain storm was approximately in 1852 when
a scientist named Robert Angus invented the term “acid rain” that means
polluted rain. Acid rain increases the acidity of soil and water which affects
vegetation growth and also kills fish. Regular
rain water will have a pH (which is a way to measure water acidity) of 5.5
because carbon dioxide will get into the rain and pollute it. If water is pure like drinking water it has a
pH of 7.0. Acid rain has a pH of anything less than 5.5. Since 2000 in the
