Ph是什麼意思

"PH" 通常指的是 "potential of hydrogen"，也就是氫離子濃度指數，是用來表示溶液的酸鹼度。PH 的值是一個介於 0 和 14 之間的數，其中：

• PH = 7 indicates a neutral solution (neither acidic nor basic).
• PH < 7 indicates an acidic solution (more hydrogen ions than hydroxide ions).
• PH > 7 indicates a basic or alkaline solution (more hydroxide ions than hydrogen ions).

The lower the PH, the more acidic the solution, and the higher the PH, the more basic the solution.
