Objectives

Development of laboratory skills and interpretation, discussion, treatment and presentation of experimental results, both individually and as a group. Integration of the knowledge introduced and apprehended in the curricular units Laboratory of Chemistry I (Q1003), Chemistry I (Q1009) and Chemistry II (Q1011).

Learning outcomes and competences

Ability to perform the most usual operations in a chemistry laboratory as well as to treat and discuss the obtained results.

Working method

Presencial

Program

This course consists of practical classes with 2 hours each, in which the following practical assignments will be carried out, according to the following schedule:

Class 1 – Course presentation and operation and assessment rules (6-10 February).
Classes 2, 3 e 4 – Practical works (13-17 e 20-24 February and 6-10 March).
Class 5 – Report of one of the practical works carried out in previous classes (13-17 March).
Classes 6, 7, 8 e 9 – Practical works (20-24 e 27-31 March, 3-7 e 17-21 April).
Class 10 – Report of one of the practical works carried out in previous classes (24-28 April).
Class 11 – Discussion of the reports. Clarification of doubts (1-5 May)
Classes 12 e 13 – Practical individual assessment (15-19, 22-24 May)

Practical Activities:

1. Titration of an aqueous solution of HCl with borax


2. Recycling of aluminium


3. Determination of the rate constant of the methyl acetate hydrolysis reaction


4. Gravimetric determination of calcium in limestone


5. "Iodine clock" reaction – method of initial rates


6. Determination of the molar enthalpy of formation of solid ammonium chloride


7. Electrochemistry experiments: galvanic cells and corrosion

Eligibility for exams

The classes of this curricular unit are mandatory. To obtain eligibility the student needs to attend ¾ of the classes, and have a positive evaluation in 2/3 (5 out of 7) of the practical laboratory activities.

Calculation formula of final grade

Due to its practical character, the discipline relies only on distributed assessment, and has no final exams.

The student must obtain positive grades in at least 2/3 of the laboratory assignments. The grade for each practical assignment (group work) is calculated based on their preparation, laboratory performance and on the respective report. The average of the classifications obtained in the n (n ≥ 5) practical assignments leads to a grade designated by NTP.

The laboratory grade (NLAB) is calculated using NTP and the grades of two complete reports (NR1, NR2), according to the following equation:

NLAB=0.70 NTP + 0.15 NR1 + 0.15 NR2

As additional evaluation element, each student having NTP ≥ 10 will have an individual practical assessment, with a numerical grade (NPI), which cannot be < 8 (out of 20). The final grade is calculated as

NF = 0,60 NLAB + 0,40 NPI

To obtain approval, the following requirements have thus to be fulfilled: NTP ≥ 10 (out of 20), NLAB ≥ 10 (out of 20), NPI ≥ 8 (out of 20) and NF ≥ 10 (out of 20).

Classification improvement

Given the laboratory nature of this curricular unit, the different evaluation components can only be improved by a new frequency of the curricular unit in another school year.
