Learning objectives
Knowledge of the concepts and methods of univariate statistic useful for chemical applications. Use of software for data elaboration. Knowledge of data elaboration. Capacity of data interpretation.
Knowledge of the role of potentiometry and voltammetry in analytical chemistry (advantages/disadvantages of these techniques)
Knowledge and understanding: the students will acquire: 1) information about the analytical methods used for the characterization of chemical compounds; 2) information about the procedures used for data elaboration
Applying knowledge and understanding: the students will be able to: i) prepare standard solutions at known concentration; ii) obtain, elaborate and evaluate scientific data by applying the correct experimental procedure and by using the most common operative systems and software
Making judgements: the students will be able to evaluate the results obtained. They will be also able to discuss the data acquired during collaborative trials, to perform experiments and to correlate data with those obtained by performing theorical evaluations.
Communication skills: the students will be able to expose their thinking in a correct way. They will be able to cooperate with colleagues, thus promoting their activities also by using multimedia tools.
Learning skills: the students will be supported in their academic achievements thanks to their capability of working both individually and on a team, thus being able to achieve specific targets.

Teaching methods
The course develops in 72 hours of frontal teching during the which the students are guided to the understanting of the concepts of both chemometrics and voltammetry, potentiometry. The students must participate to the computer lessons. During these lessons students will be able to understand how data have to be processed and evaluated.
Assessment methods and criteria
Written and oral examination to verify the acquisition of basic concepts of chemometrics for data elaboration and interpretation. Knowledge of potentiometry, voltammetry and other electrochemical techniques for the right choice of analytical methods
Witten examination (15 min duration) will be carried out on significant digits. Results will be communicated to the student by ESSE3 platform
Oral examination (30 min duration) will be on the entire topics of the course. Results will be orally communicated and inserted in the ESSE3 system
In cases of failure to respond (3 questions), students will fail the exam
Other information
Educational material is available to the students
