General and Inorganic Chemistry with Lab
A.Y. 2023/2024
Learning objectives
The aim of the course is to introduce the basics of chemistry from both a theoretical and a practical point of view. The course is splitted into two parts, with classroom lessons, stoichiometry and laboratory practice.
Expected learning outcomes
The student will be able to understand the basics of chemistry both in its theoretical and practical aspects.
Lesson period: First semester

Prerequisites for admission
No preliminary knowledge required
Assessment methods and Criteria
Two written tests. The General and Inorganic Chemistry part consists of 20 questions, most of which with multiple choice. The Laboratoty parts consists in 5 stoichiometry problems dealing with the whole programm, in the aim to check that the student has not only acquired notions, but has also gained the skill to elaborate them. For each of the two tests the student has an allotted time of two and half hours. The final grade is a number in the 1-30 range. There are two intermediate tests for each part of the course. A positive grade in both tests of a part of the exam substitute the final test.

Chemical equilibrium: equilibrium constants expressed in terms of concentration, pressure, moles and molar fraction. Effect of concentration, pressure and temperature variations on chemical equilibrium. Ionic equilibria in aqueous solution: strong and weak electrolytes; neutral, acidic and basic solutions; pH and pOH. pH calculation for weak and strong acids and bases. Acid and base mixtures: hydrolysis and buffer solutions. Simultaneous equilibria. Complexometry. Precipitation equilibria: solubility and solubility-product constant. Effect of the presence of a common ion, of the pH, and of complexation on precipitation equilibria.
Lectures (2 CFU, 16 hrs) are supported by numerical exercises held in classroom, and by laboratory experiences, for a total amount of 4 CFU (64 hrs).
The single-bench practical laboratory experiences include: synthesis of the Mohr's salt; synthesis and crystallization of PbI2; copper cycle; synthesis of alum from aluminum foil.

Teaching methods
Lessons and stoichiometry exercises are parly made on the blackboard an partly by using Powerpoint presentations. The latter are available on Ariel. Laboratory practise is made individually by each student in a properly equipped laboratory. Attendance to laboratory experiments is mandatory. Attendance to lessons and classroom exercises is strongly recommended.
