PRACTICES OF LABORATORY (14 hours)
includes in this epigraph the realisation of a project. |
PL1. CHEMICAL BALANCE: LE CHATELIER´S PRINCIPLE
Two reversible reactions will be studied, that have the advantage of the great ease with which the presence of reactants and products are detected, caused by color changes or by the appearance of a precipitate.
PL2. ACID-BASE TITRATION: TITRATION CURVE
Acid-base titrations are very useful to accurately determine the concentration of an acid/basic solution by adding a base or an acid of known concentration. Specifically, the assessment of a strong base with a strong acid will be carried out, for which different amounts of acid will be added and the pH of the resulting solution will be measured. In this way, the corresponding "titration curve" will be obtained and the pertinent conclusions will be drawn.
PL3. REDOX AND ELECTROCHEMICAL PROCESSES: ELECTROLYSIS
In order to become familiar with the chemical changes induced by an electric current and with the quantitative relationships involved, students will carry out the following experiences: Electrolysis of aqueous CuSO4(aq) and electrolysis of NaCl(aq).
PROJECT
Five laboratory sessions will be dedicated to the project, with the following estimated distribution:
P1. Presentation of the project: Proposal for treatment systems for ballast water.
P2-3 Experimental work in the laboratory.
P4 Preparation of the report-
P5 Presentation of the results. |
