SDGs

This teaching activity contributes to the achievement of the Sustainable Development Goals of the UN 2030 Agenda.

Quality education

Academic Year 2021/2022

Learning outcomes

The students acquire the basic knowledge of laboratory tools and techniques. In particular they learn how to: safely handle chemical substances, use IUPAC nomenclature and IS units, perform stoichiometric calculi and prepare solutions, collect and process experimental data, correlate experimental data with theory.

Course contents

The course has compulsory attendance. To attend the experimental activities of the Chemistry Laboratory course, it is compulsory to attend the lectures held before the beginning of the laboratory. Furthermore it is compulsory to attend the lessons on Safety in the Chemistry Laboratory.

Safety in chemistry laboratories. Basic laboratory equipment and techniques.

Introduction to laboratory exercises:

1. Chemical reactions - Precipitation, acid-base, complexation and redox reactions.

2. Solubility constant of a silver salt.

3. Synthesis of inorganic compounds - Mohr salt, double salt of Co, Potassium alum - Stoichiometry.

4. Copper reactions - Stoichiometry - Redox, precipitation, acid-base, complexation reactions.

5. Determination of an equilibrium constant - Spectroscopic method.

6. pH Indicators.

7. Acid-base titrations.

8. Buffers.

9. Redox titrations.

10. Determination of equilibrium constants with electrochemical measurements.

Readings/Bibliography

Laboratory procedures will be available on line.
The topics of this course can be found in any university textbook of General Chemistry. See, for example:
Steven S. Zumdhal, "Chimica", Zanichelli.

Teaching methods

The lectures will cover the general issues related to laboratory activity: safety, language, design, data processing.The course also includes practical laboratory exercises aimed at:

- developing basic skills required to carry out laboratory activities

- verifying by way of experiments some of the topics presented during the lectures of general chemistry.

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] online, while Module 3 on health and safety is to be attended in class. Information about Module 3 attendance schedule is available on the website of your degree programme.

Assessment methods

Practical examination (in case of restrictions, oral examination).

Reports on the practical lab exercises.

The final mark is the weighted arithmetic mean between the reports (25%) and the examination (75%)

Teaching tools

Blackboard. On- line lessons according to the instructions of the University.

General and inorganic chemistry laboratory of the Chemistry Department. In order to access the laboratory, students must wear their own lab coat.

The access to the laboratories takes place in compliance with the rules approved by the Department
