Detailed explanation-1: -Some acid rain occurs naturally, but sulfur dioxide and nitrogen oxide emissions from smokestacks combine with rain to make sulfuric and nitric acid in amounts that harm the environment. The region of the United States most harmed by acid rain is the East Coast, including the Appalachian Mountains and the Northeast.

Detailed explanation-2: -The areas of greatest acidity (lowest pH values) are located in the Northeastern United States. This pattern of high acidity is caused by the large number of cities, the dense population, and the concentration of power and industrial plants in the Northeast.

Detailed explanation-3: -Most of the acidic and acid-sensitive surface waters in New York State are located in the Adirondack and Catskill regions.

Detailed explanation-4: -According to some reports published in the New York times, the Massachusetts state in the United States of America has the most acidic rain. The pH value of the acid rain is 4.1, which is slightly higher than the pH 3 value of vinegar. The pH value of the normal water is 5.6.

Detailed explanation-5: -The story of acid rain from the 1970s is preserved in newspaper headlines, textbooks, and, it turns out, the soils of the northeastern United States. Forty years after humans first began tackling the problem, the impact of acid rain still lingers in New York, Vermont, New Hampshire, and Maine, according to a new study.
