Not all rain can be considered pure water. Pure water is neither alkaline nor acidic. As rain falls from the atmosphere the impurities it collects changes the pH of the rain water, making it slightly acidic. The pH of water determines if it is acidic or alkaline.

Rainfall is greater in these areas of the country, and over time, rain leaches away the alkaline elements in soil, creating a more acidic soil. In addition to receiving more rainfall than other areas of the country, these regions have more tree cover as well. Fallen leaves and pine needles slowly decay and contribute to the acidic level of the ...

Acid rain (AR) can be defined as a combination of dry and wet deposition from the atmosphere having higher than normal concentrations of nitric (HNO 3), sulfuric acids (H 2 SO 4), and acidifying compounds which lead to a decrease in the pH of rainwater to less than 5.61.In 1845, AR was first been mentioned by Ducros, although a detailed …

The lower the number, the more acidic the water is. The higher the number, the more basic it is. A pH of 7 is considered neutral. The logarithmic scale means that each number below 7 is 10 times more acidic than the previous number when counting down. Likewise, when counting up above 7, each number is 10 times more basic than the previous ...

The classic examples are with phenol (C 6 H 5 OH) which is about a million times more acidic than water, and with acetic acid (pK a of ~4). Watch out though – it isn't enough for a π system to simply be adjacent to a proton – the electrons of the conjugate base have to be in an orbital which allows for effective overlap.

The problem is that acid-causing substances have built up in the ground and are still causing cascading chemical effects that could continue for decades. The first good evidence of acid rain's long-term effects came in 1996 from New Hampshire's Hubbard Brook Experimental Forest, where data have been collected since the early 1960s.

Acid rain is measured using a pH scale for which 7.0 is neutral. The lower a substance's pH (less than 7), the more acidic it is; the higher it is (greater than 7), the more alkaline it is. Normally, rain has a pH of about 5.6, making it slightly acidic because CO2 dissolves into it, forming a weak carbonic acid.
