ALESSANDRO D'URSO


Learning Objectives

The aim of the course is to complete and re-enforce the arguments of General Chemistry, which will serve as cultural baggage to address the subsequent teachings.

It is the place where you learn to enter probably for the first time in depth within the chemical processes with particular attention to the reactions in the gas phase or aqueous solution.

In this second part of the course the water solution equilibria, the electrochemistry will be treated with particular attention and will also give an outline of Inorganic Chemistry.


Course Structure

Initially the course will includes a large number of lectures to deal with about 2/3 of the topics.

Then the lectures will be combined with laboratory hours where the students will put into practice the concepts addressed in the front lectures.

Finally, a session of numerical exercise facing problems on the topics covered in lectures will be provided

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus



Detailed Course Content

1. Ionic equilibria in aqueous solution: Acid and base, pH, solubility of salts and solubility product.

2. Electrochemistry: conductivity of aqueous solutions, electrolysis, Faraday laws, piles and normal potentials of semi-elements, use of normal potentials for the prediction of a redox reaction, overvoltage and discharge potentials.

3. Inorganic chemistry: hydrogen and elements of the s group, alkaline and alkaline-earth metals, elements of the p-block: outlines on the third group, fourth group, fifth group, sixth group (the calcogens), seventh group (the halogens), outline on rare gases.

5. Exercises: - Solubility and solubility product (Definition of solubility product constant Relationship between solubility of salts and their solubility product for salts of different stoichiometry)

- Calculation of the pH of acid/base solutions, buffer solutions and salt solution

- Electrochemistry (Calculation of the E ° of a redox reaction and of the relative equilibrium constant, calculation of the quantities obtained from electrolysis of saline solutions and molten salts)

6. Laboratory experiences: 1) Titrations of strong monoprotic acids and also pH-metric

2) Solubility of salts (determination of solubility product of a slightly soluble salt and solubility test of silver halides in ammonia

4) Construction of a battery and electrolysis of aqueous solutions

6) Permanganometric titration of hydrogen peroxide and a detergent containing sodium percarbonate

All the topics covered are considered indispensable for passing the exam.
