Content

First, a seminar to explain the contents and methodology used in this subject will be programed.
Afterwards, students will have to complete 12 laboratory sessions of 4 hours each, during which they will carry out a set of laboratory practices that have to be previously prepared with the guide (and other materials) published in the virtual campus.
Practices will include advanced kinetics, electrochemistry, surface phenomena, and any other phenomena in the field of Experimental physical chemistry
 
The laboratory session will delve into topics seen in previous theoretical subjects, but  the laboratory can also be used to introduce aspects not seen before.

The following is a likely list of practices as an example, even if the professors in each academic year can modify them or select others.
-Kinetics by Polarimetry. Inversion reaction of sucrose.
-Kinetics fby conductimetry. Basic hydrolysis of ethyl acetate
-Iodation of cyclohexanone in acidic medium: kinetic study.
-Solvatocromism as a tool to characterize a solvent's properties.
-Adsorption isotherm
-Conductivity of ionic dissolutions
-Determination of the critical micellar concentration by means of conductivity measurements.
-Sewage treatment through electrochemical processes
-Surface tension. Wettability.

Before starting the laboratory sessions, there will be a session in the lecture room to explain the rules that appear in this teaching guide, and give last minute information and the specific methodology and contents.

Attendance at the classroom and laboratory is mandatory. An unjustified lack implies a zero in a practice.
The students, in groups of 2 students whenever possible, will perform 12 lab sessions lasting 4 hours, during which a 9-10 different practices shall take place.

Students will previously have the scripts for the practices for its preparation. They must enter the laboratory with the script of the practice read and the calculations, tables etc. prepared in the laboratory notebook.

At the begining of each lab session, a pre-lab test will be done, individually, to evaluate the level of preparation of the sesison.
Students must correctly transfer all the experimental results elsewhere.

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Writen exam 30% 4 0.16 4, 7, 8, 42, 41, 40, 39, 57, 13

The evaluation process follows the principle of continuous assessment. The overall grade will be the mean of the two blocks, A and B, that form the lab.

For each block, the mark will be constituted by the weighted sum of 3 items:

  •  Evaluation of the preparation of the practices: pre-lab test (10%).
  • Report marks (60%).
  • Written exam (30%).

To do the average you must obtain a mark equal to or greater than 4.0 in the exam. If the minimum mark of 4.0 is not obtained, a recovery exam will be available. If the mark of  4.0 is not reached in the recovery, the student will be deemed suspended and the record will be the mark of the suspended exam.
To participate in the recovery, students must have been previously evaluated in a set of activities whose weight is equivalent to a minimum of two thirds of the total qualification of the subject and has obtained a global qualification equal to or greater than 3.5.

If the student has been evaluated of a number of evidences whose weight doesn't reach the 25%, the qualification obtained will be "NON EVALUABLE".

This subject is out of the "single-evaluation" choice.
