| Abstract: | In the teaching of analytic experiments,we have found that the similar phenomena occured in identifying the co-existence of argentous ion & manganous ion and identifying the mercurous ion by using sulfureted hydrogen systematic analysis way for unknow caton.This phenomenon causes the additional identify cation of mercurous ion.We analyse the reason and find the solution by experiments. |

| Keywords: | sulfureted hydrogen systematic analysis way mercurous ion additional identify coprecipitation |
