Learning outcomes

All the specific learning outcomes are available on the SCHIB112 WebCampus page. Only the intermediate learning outcomes (i.e. grouping together specific learning outcomes relating to the same theme) will be developed here. On completion of the course, students will be able to :

- quantitatively determine the pH of various solutions, whether or not resulting from a mixture of substances, in aqueous solution ;

- draw and use a titration curve relating to the titration of a strong acid, a weak base, a weak acid, a weak base, an ampholyte and mixtures of substances, in aqueous solution ;

- draw and use a balance diagram of the quantities of different chemical species, relating to the titration of a strong acid, a weak base, a weak acid, a weak base, an ampholyte and mixtures of substances, in aqueous solution ;

- draw and determine the forms (positively charged, zwitterionic, negatively charged) of a given amino acid at different pH values, and use them to solve qualitative and quantitative problems.

- apply the conditions required to optimise the buffering capacity of a buffer.

- apply Ostwald's law to quantitative problems in aqueous solution.

- quantitatively solve stoichiometric problems involving the weighting of redox or acid-base reactions in aqueous solution.

- apply the conditions for carrying out a quantitative acid-base reaction, oxidation-reduction reaction, precipitation reaction or complexation reaction, using a table of data (Ks, Ka, Ki, Kd).

- determine the solubility of an insoluble substance from its Ks

- quantitatively determine the total, temporary and permanent hardness of a mineral water or extract the concentrations of calcium, magnesium and bicarbonate ions from these data.

- describe the structure and explain the mechanism of various batteries

Goals

Objectives (in terms of skills) The objectives of this course are to

• to give the student a rigorous basic formation in all aspects of General Chemistry in aqueous solutions;

• contribute to the description of matter and reactivity of compounds (pure bodies or mixtures) ;

• explain according to the three levels of knowledge (macroscopic, microscopic and symbolic) and predict chemical transformations using different theoretical concepts;

• solve problems using mathematical reasoning and tools, in real-life situations;

• interpret data presented in different forms (table, graph, text, etc.)

Content

This course develops the fundamental theories of the chemistry of reactions in aqueous solution (dissociation, acid-base, redox, precipitation, complexation). After defining the profile of reactants in aqueous solution, the thermodynamic concepts studied in SCHIB111 will be applied to estimate the progress of reactions. Different applications of these reactions will be described.

Assessment method

The course will be assessed by a written exam in the June session. Students will be asked to answer several questions (MCQs) integrating theory, exercises and learning from the practical work. A single mark will be awarded for this assessment.

This mark will include 10% of the mark obtained at the end of the practical activities.

Attendance at the practical exercises is required ; any unjustified absence will be penalised by a 0/20 for the laboratory concerned. In the event of justified absence, the student must contact the la cellule didactique de chimie (didactique.chimie@unamur.be) by e-mail within three  days following the end of the medical certificate or the justification to recover the missed laboratory in another group. If this is not done, the student will receive a 0/20 for the missed class. The credits will be validated if the mark is equal to or higher than 10/20. In the second session, the organisation will be identical.
