CO2含量%PH值%酸雨
CO2含量%PH值%痠雨
CO2함량%PH치%산우
CO2 content%PH value%Acid rain
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。
正常雨水的PH值約為5.7左右。痠雨是指PH<5.6的降雨。本文利用化學平衡常數根據公式對雨水中的PH值進行瞭估算，併推導齣CO2分壓與ph值的關繫，從理論上推導齣CO2濃度升高會引起水中氫離子濃度的增大，從而最終導緻雨水中ph值下降。指齣噹二氧化碳的濃度達到一定的濃度，人們將麵對除溫室效應以外的更深遠的影響。

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.
