The Chemistry Lab (Q1005) course comprises execution and/or visualization of a set of practical works, involving several experimental techniques and basic procedures in experimental Chemistry.
Providing the students with a basic training in chemistry laboratory techniques to be executed and/or visualized.
It is intended that at the end of the semester the student has acquired the following basic skills: to understand how a set of basic unit operations in laboratory chemistry should be correctly performed; to interpret experimental results and prepare written reports of experimental activities.
This course is exclusively composed by lab classes, where students are invited to carry out a number of experiments allowing them to become proficient in most of the unitary operations in experimental Chemistry. Yet, in the exceptional case that presential activities are not possible, experimental activities will be replaced by relevant support materials (e.g., videos, and others), to be made available through the Moodle platform.
PRESENTATION OF THE SCOPE, RULES AND EVALUATION METHODS - 1st CLASS
1. Introduction to the course. Safety rules in the lab.
2. Introduction to basic chemistry calculations and lab operations.
LABORATORY EXPERIMENTS (2 h/week) - following classes
PL1 – Preparation of solutions of approximate and rigorous titer.
PL2 – Purification by recrystallization.
PL3 - Spectrophotometric quantitation of a food colorant.
PL4 – Destilation of a water-acetone mixture.
PL5 - Spectrophotometric quantitation of a food colorant.
PL6 – Strong Acid-strong base titration.
PL7 – Strong Acid-weak base titration.
FINAL INDIVIDUAL EVALUATION
- individual practical examination, where each student will be attributed (part of) one laboratorial activity to execute experimentally; this evaluation will take place in the last couple of weeks of the academic year. In the exceptional case that presential activities cannot be carried out, the practical examination will be replaced by an individual written test, focusing the experimental techniques addressed in the course, as well as the underlying concepts and calculations.
Laboratory practices and/or supporting materials made available through the Moodle UPorto online platform.

In this practical course it is mandatory to attend classes.
In order to be admitted for final individual evaluation (practical or written, depending on circumstances), and apply for approval at this course, students must attend a minimum of 75% of the total number of planned classes (presential and/or remote), and get a positive assessment on at least 6 out of the 7 reports to be ellaborated and submitted for evaluation.
Students admitted to the individual written test who fail to attend it will be given a zero mark to the test.
NF = 0.70 x NP + 0.30 x NI
where NP is the averaged evaluation from the written reports (1 per group) on lab experiments, and NI is the mark obtained in an individual test (practical or written, depending on the circumstances).
Only students having complied with the attendance requisites specified in the previous field, and having scored an NP ≥ 9 will be admitted to the individual test. There will be no minimum NI score to be approved, and not attending the individual test will correspond to NI = 0 (zero). Approval to the course is only possible when NF ≥ 9.5.
