摘要
本法系在氨盐缓冲溶液中进行,不形成 Mg(oH)_2沉淀,终点变化敏锐;另外,一份溶液中同时滴定钙、镁,方法简便、快速、准确、经济。
The measure is carried out in the buffer solution containing ammoniac salt. There is no Mg(oH)_2 precipitate formed in the testing process,and the corresponding varia- tion of the titration end-point is sensible.In addition.It is more rapid,accurate,economic and simpler than other methods due to its simultaneous titration to calsium and magnesium ious in one part of the Solution.
