The pH of Water

pH is a term used rather universally to express the intensity of the acid or alkaline condition of a solution. It is a way of expressing the hydrogen-ion concentration, or more precisely, the hydrogen-ion activity.

Carbonic acid, formed by the reaction of CO2 and water in the atmosphere, is picked up in the normal precipitation process, so that rainwater is typically at about a pH of 5.6.

Rain, with its normally small amount of carbonic acid (H2CO3), dissolves the CaCO3 present and forms calcium bicarbonate. The calcium bicarbonate is a source of CO2 for photosynthesis by green plants.

The pH of Water
水的pH值
pH is a term used rather universally to express the intensity of the acid or alkaline condition of a solution. It is a way of expressing the hydrogen-ion concentration, or more precisely, the hydrogen-ion activity.
pH值是一个术语,而普遍表达的强度的酸或碱性条件一个解决方案。这是一个表达氢离子浓度的方法,或者更准确地说,氢离子的活动。
Carbonic acid, formed by the reaction of CO2 and water in the atmosphere, is picked up in the normal precipitation process, so that rainwater is typically at about a pH of 5.6.
由反应形成碳酸,大气中的二氧化碳和水,是捡起在正常降水过程,所以雨水通常是在pH值为5.6左右。
Rain, with its normally small amount of carbonic acid (H2CO3), dissolves the CaCO3 present and forms calcium bicarbonate. The calcium bicarbonate is a source of CO2 for photosynthesis by green plants.
通常下雨,少量的碳酸(H2CO3),溶解碳酸钙现在和碳酸氢钙形式。碳酸氢钙是由绿色植物来源的二氧化碳进行光合作用。
