The typed lab report for the qualitative analysis of group i cations lab should be relatively short make sure you include your unknown number or letter in the conclusion (ie state something like unknown x.
The cations to be studied include some common alkaline earth metals, group 13 and zn 2+ these ions are not colored in solution, and most of their compounds are white it is impossible therefore to use colors of solutions or precipitates to indicate which of these cations is present in solution. Qualitative analysis – group i cations lab report qualitative analysis cations and anions essays and research papers lab report qualitative analysis for in addition, a problem-solving oriented experiment can stimulate students to. Knowing the actual results of the reactions characteristic for a given cation (or a group of cations) makes it easier to identify this ion in the unknown sample, when the same results are obtained in a test.
Qualitative analysis lab report separation of group i cations: ten drops of the unknown solution c were placed into a small test tube four drops of 6 m hcl were added to the unknown solution (aq) solution this lab uses no quantitative analysis, but is entirely based on qualitative analysis which is the observed result instead of the.
