ＰＨ值的计算方法赵家标一、单一溶液ＰＨ值的计算１．利用ＰＨ＝－ｌｇ［Ｈ＋］。例。０．００５摩／升的氢氧化钡溶液中，ＰＨ值是多少？解：∵［ＯＨ－］＝１０（－２）摩／升∴［Ｈ＋］＝１０（－１２）摩／升。故ＰＨ＝－ｌｇ［Ｈ＋］＝１２。注意事项：①如果题目给...
Calculation Method of PH Value Zhao Jiabiao 1. Calculation of single solution PH value 1. Use PH=-lg[H+]. example. What is the PH value in the 0.005-mole/liter rhodium hydroxide solution? Solution: ∵ [OH-]=10 (-2) friction/liter ∴ [H+]=10 (-12) friction/liter. Therefore, PH=-lg[H+]=12. Matters needing attention: 1 If the title to...
