Objectives
LEARNING OBJECTIVES: STUDENTS WILL ACQUIRE THE BASIC SKILLS USEFUL TO PERFORM ALL THE OPERATIONS TYPICAL OF A CHEMISTRY LABORATORY TOGETHER WITH THE SCIENTIFIC PROCEDURES TO CARRY ON EXPERIMENTS.

THE MAIN COMPETENCES TO GAIN ARE:
•CORRECT USE OF GLASSWARE;
•INSTALLATION AND USE OF SIMPLE EQUIPMENT FOR THE PREPARATION, SEPARATION, PURIFICATION AND CHARACTERIZATION OF CHEMICAL COMPOUNDS;
•USE OF THE ANALYTICAL BALANCE;
•ASSESSMENT OF THE ERROR ASSOCIATED WITH THE MEASUREMENT;
•DATA ANALYSIS;
•USE OF SOFTWARE FOR VISUALIZATION OF MOLECULES AND EXPERIMENTAL DATA.
Prerequisites
PREREQUISITES:
FUNDAMENTALS OF MATHEMATICS AND CHEMISTRY THAT CAN BE ACQUIRED AT SECONDARY SCHOOL LEVEL; BASIC KNOWLEDGE OF ENGLISH.
Contents
CONTENTS/PROGRAM:
THE COURSE IS DELIVERED ON AN ANNUAL BASIS AND DIVIDED INTO TWO TEACHING MODULES; CHEMISTRY LABORATORY MODULE A (ANALYTICAL, GENERAL AND INORGANIC CHEMISTRY, I SEMESTER); CHEMISTRY LABORATORY MODULE B (PHYSICAL CHEMISTRY, ORGANIC CHEMISTRY, II SEMESTER).
THE COURSE CONSISTS OF CHEMISTRY LABORATORY EXPERIENCES AND COMPUTER EXPERIENCES.

THE TOPICS COVERED WILL BE:
MODULE A: GENERAL AND INORGANIC CHEMISTRY AND ANALYTICAL CHEMISTRY (36H)
• TYPES OF GLASSWARE AND THEIR USE;
• EWC CODES (EUROPEAN WASTE CODE), CORRECT SORTING AND DISPOSAL OF CONTAMINATED CHEMICAL MATERIALS;
• ANALYTICAL SCALE: CORRECT METHODS OF USE;
• PREPARATION OF KNOWN SOLUTIONS OF SALTS AND MOLECULAR COMPOUNDS BY WEIGHING;
• PREPARATION OF SOLUTIONS OF ACIDS AND BASES BY DILUTION;
• LABORATORY TECHNIQUES FOR THE PREPARATION, SEPARATION, PURIFICATION AND CHARACTERIZATION OF CHEMICAL COMPOUNDS;
• PROPERTIES AND REACTIVITY OF INORGANIC COMPOUNDS (IN CLOSE CORRELATION WITH THE CONTENTS OF THE COURSE OF GENERAL AND INORGANIC CHEMISTRY);
• PROCESSES OF PREPARATION OR ISOLATION OF INORGANIC SUBSTANCES;
• DETERMINATION OF MOLAR MASS AND BRUTE FORMULA IN UNKNOWN SAMPLES.

MODULE B: PHYSICAL CHEMISTRY AND ORGANIC CHEMISTRY (36H)
• EXECUTION OF BASIC OPERATIONS OF PURIFICATION OF ORGANIC COMPOUNDS, APPROPRIATELY CHOSEN AMONG THE MAIN TECHNIQUES OF PURIFICATION OF COMPOUNDS: CRYSTALLIZATION, EXTRACTION WITH SOLVENTS, CHROMATOGRAPHY ON SILICA GEL;
• EXECUTION AND CONTROL OF SIMPLE ORGANIC CHEMISTRY REACTIONS CLOSELY RELATED TO THE LESSONS OF THE THEORETICAL COURSE AND ISOLATION OF THE REACTION PRODUCT;
• PRACTICE IN THE USE OF SOFTWARE FOR MOLECULAR DESIGN;
• FUNDAMENTAL PHYSICAL QUANTITIES AND DERIVED QUANTITIES; DIMENSIONAL ANALYSIS;
• ESTIMATION OF THE ERROR ASSOCIATED WITH A MEASURE. CALCULATION OF THE MEAN AND STANDARD DEVIATION; ERROR PROPAGATION FORMULAS. VARIANCE, COVARIANCE, CORRELATION COEFFICIENT;
• STATISTICAL PROCESSING OF EXPERIMENTAL DATA. APPLICATION OF THE LEAST SQUARES METHOD
• USE OF SOFTWARE FOR GRAPHICAL VISUALIZATION OF EXPERIMENTAL DATA (EXCEL, MATLAB, R);
• USE OF SOFTWARE FOR THE VISUALIZATION OF MOLECULES.
Teaching Methods
TEACHING METHODS:
THE COURSE INCLUDES THE EXECUTION IN GROUPS OF LABORATORY EXPERIENCES OR CALCULATION PROCEDURES AND THE SUBSEQUENT DRAFTING OF A LABORATORY REPORT FOR EACH EXPERIENCE, AIMED AT ACQUIRING THE SKILLS INDICATED.
THE ATTENDANCE OF THE LABORATORY IS MANDATORY FOR AT LEAST 75% OF THE TOTAL NUMBER OF HOURS AND WILL BE ASCERTAINED BY THE TEACHER WITH A CLASS ROLL. IN ADDITION, THE LABORATORY ACTIVITY MUST BE WITNESSED BY THE COMPILATION AND DELIVERY OF WRITTEN REPORTS TO THE TEACHER OF THE MODULE WEEKLY.
Verification of learning
LEARNING VERIFICATION MODES:
THE PAPERS REQUIRED AT THE END OF EACH EXPERIENCE WILL BE EVALUATED, AND THIS EVALUATION WILL CONTRIBUTE TO THE FINAL EXAM GRADE.
IT IS EXPECTED TO PASS A VERIFICATION TEST BASED ON MULTIPLE CHOICE QUESTIONS RELATED TO THE CONTENTS OF THE COURSE.

EVALUATION CRITERIA:
IN THE FINAL EVALUATION, THE BEHAVIOR HELD IN THE LABORATORY, THE EVALUATION OBTAINED IN THE REPORTS DELIVERED AND IN THE VERIFICATION TEST WILL BE CONSIDERED.
