pH

表示水溶液的酸性和堿性的度量單位。由水中氫離子(H3O+)濃度的對數的負數來定義。如果pH值為7溶液是中性的,pH小于7是酸性的,pH大于7是堿性的。

 

pH

Measures the acidity or the basicity of an aqueous solution. It is defined by the inverse of the log of the concentration of hydronium ion (H3O+) in water. A solution is neutral if the pH value is 7, acidic if the pH is less than 7 and basic when the pH value is higher than 7.
