PROGRAM
Theoretical Classes
1. Qualitative Analytical Chmenistry determines the presence of spcecificspecies in a sample.
2. Systematic analysis of a solution: identifcation and separation of anions and cations.
3. Systematic analysis of cations
Group Reagent notion.
Classification and separation of cations in diferent groups.
Specific Reaction of each group
Characterisation reaction of each cation
- group I : Ag+; Pb2+; Hg22+.
- group II : Hg2+; Pb2+;Bi3+; Cu2+; Cd2+; As(III); As (V); Sb (III); Sb (V); Sn2+; Sn3+ e Sn4+.
- group III: Cr3+; Al3+; Fe3+; Ni2+; Co2+; Zn2+; Mn2.
- group IV: Ba2+ e Ca2+ Sr2+.
- group V: Mg2+ ; NH4+; Na+ ; K+
