| 摘 要： | 正常雨水的PH值约为5.7左右。酸雨是指PH〈5.6的降雨。本文利用化学平衡常数根据公式对雨水中的PH值进行了估算,并推导出CO2分压与ph值的关系,从理论上推导出CO2浓度升高会引起水中氢离子浓度的增大,从而最终导致雨水中ph值下降。指出当二氧化碳的浓度达到一定的浓度,人们将面对除温室效应以外的更深远的影响。

| Abstract: | Normal rain PH of about 5.7 or so. Acid rain refers to PH 〈 5.6 of rain. This paper, by using the chemical equilibrium constant according to the formula to estimate, the PH of rain water and CO2 partial pressure and PH value is deduced, the relationship between elevated CO2 concentration is deduced theoretically will cause the increase of hydrogen ion concentration in water, which eventually led to the decrease of the PH in the rain. Pointed out that when the concentration of carbon dioxide reaches a certain concentration, people will face a more profound influence on other than the greenhouse effect. |
