Evaluation method

Frequency 
Obtaining frequency requires that students attend all 
practical classeand 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
