Electrode potentials; standard reduction potentials. Reference electrodes. The electrochemical series: redox properties of metals according to their electrode potentials; connections with metal corrosion.
Course Practicals
The laboratory part of the course will include practicals on the structure of chemical compounds, preparation, dilution and mixing solutions, the acid-base properties of certain chemical compounds, the titration of weak acids and bases and buffer solutions; the redox properties and the solubility product of salts.
COURSE AIMS AND OBJECTIVES
The Scope of the Course
To convey a solid chemical background so that students are able to qualify and quantify various stimuli from the entire body of natural science.
Course objectives
The students are expected to understand the basic concepts related to the structure of matter at the atomic and molecular level; to clarify the chemical basis of the physical states of matter: solids, liquids and gases; to elucidate the acid/base and oxidative/reductive behavior of certain compounds and elements; to develop the requisite laboratory skills for safe handling of common chemicals and using these for the study of chemistry-related issues. STUDENT ASSESSMENT The student’s final grade results from 50% of the grade of the theoretical part and 50% of the grade of laboratory practice. Language of evaluation: Greek ΤΗΕΟRY (50%): Written exams: • Open-ended questions • Multiple-choice questionnaires • Short-answer questions LAB PRACTICES (50%): Written essays ATTACHED BIBLIOGRAPHY Greek and Translated into Greek 1.
