Error of Acid Rain Research, Effect of Atmosphere CO₂ Ignored

Abstract:

Since the concept of acid rain was come up with time has been for a little more than a hundred years. Many researchers have studied the causes of it formation and obtained some results. But a satisfactory explanation can not be given about some phenomena of acid rain until today. For example in some regions the acid substances in atmosphere before formed acid rain are being reduced year after year but acidity of rainwater and acid rain frequency are being increased year after year. The anions are less than cations in acid rain, and so on. In order to solve these problems we have done simulated tests. Here we show that the cause of unaccountability some acid rains is ignored effect of atmosphere CO₂. Firstly, CO₂ is well-known acid substance, it can make water acid and its amount is ten thousand times as much as other acid substances, for example SO₂ and NO_x, in atmosphere. Then, when CO₂ was not dissolved in solution of simulated acid rain pH of solution was larger than 6 although the ions percentage composition of solution is as same as acid rain, and when CO₂ was done pH of solution was less than or equal 4.6. So, we concluded that CO₂ plays an important role in acid rain forming.
