| 摘 要： | 采取ＰＨ电位滴定法直接测定铵盐中含氮量。在此滴定中仅需滴定至ＮＨ＋离解度大于１０％以上即可，不需要将ＮＨ＋用ＮａＯＨ标准溶液滴定至超过等当点。 |
| 关 键 词： | PH滴定 铵盐 氮 电位滴定 |

| Abstract: | The present PH potentialmetric method is determining in extremely weak acid.Themethod needs only to titrate more than ten per cent of ionization of It is not necessary tochange a hundred per cent of into NH3 by titration of NaOH. |
| Keywords: | PH titration.Ammonia salt.Distribution wefficient. |
