Evaluation method
Frequency
Obtaining frequency requires that students attend all
practical classes and all theoretical classes.
Final grade
The final grade will result from continuous assessment
throughout the practical and theoretical classes, from the
presentation of a poster (size A0) with the results obtained
from Practical Work No. 6 and a final exam.
Final Grade:
laboratory notebook 10%
laboratory performance 10%
pre lab and post lab questionnaires 10%
presentation of the poster 30%
final exam 40%
Subject matter
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+
4. Qualitative Inorganic Analysis
Laboratory classes:
1st Class – Solubility and Flame Tests
2nd Class -Separation and identification of Group I cations: Ag+; Pb2+; Hg22+
3rd Class -Separation and identification of three cations of subgroup IIA:
Cu2+; Cd2+; Bi3+,
4th Class - Separation and identification of five cations from Group III
: Cr3+; Al3+; Fe3+; Ni2+; Co2+
5th Class - Separation and identification of two cations from Group IV: Ba2+ e Ca2+
6th Class - Separation and identification of cations in an unknown sample
