We had A known and we checked it for pb^+2, hg2^+2, and ag^+1.
Which is the correct lead for anion confirmation test?
The analysing of group is done by adding the respective salt into water and follow it with dilute HCl. This results in a white precipitate in which NH4OH is added. The insoluble precipitate shows the presence of Plumbous (Pb2+) and if precipitate is soluble, and then it shows the presence of Argentous (Ag+).
How are Group I cations separated from other cations?
Group I Cations Cations: Ag+, Hg22+, and Pb2+ Group I cations can be separated from the other groups since they form slightly soluble chlorides with the addition of hydrochloric acid (generally 1- 2 M concentration). The other groups will remain in solution thus allowing the Group I chloride precipitates to be removed and further tested.
How are cations and cations determined in qualitative analysis?
Qualitative analysis is a type of chemical analysis which is used to separate and detect cation and anions in a sample substance. The chemical properties of an unknown substance are determined in the qualitative analysis procedure by the reaction between the unknown substance and suitable reagents.
