KNOWLEDGE:

• The student knows and understands the physical principles of instrumental methods, i.e., absorption, nephelometry, turbidimetry, flame photometry, spectrofluorimetry, spectrography and emission spectrometry, atomic absorption spectroscopy, gas and liquid chromatography, mass spectrometry, conductometry, potentiometry, electrogravimetry, coulometry, polarography, constant and alternating current voltammetric methods, and is able to list the information obtained from each of them (KP6_WG5).

• The student knows the basics of the construction and operation of a flame photometer, UV-Vis spectrophotometer, pehameter, potentiometer, conductometer, potentiostat, and electrolyzer (KP6_WG12).

SKILLS:

• The student uses the serial dilution method, converts absorbance to transmittance, determines the molar absorption coefficient, is able to determine mass and concentration based on linear regression equations, has the ability to perform calculations related to pehametry, knows the standard addition method and is able to use it, is able to correlate the mass of sediments separated during electrolysis with the chemical reactions taking place, performs calculations based on the Randles-Sevcik equation (KP6_UW1)

• The student analyzes emission and absorption spectra, recognizing and quantifying sodium and calcium ions (flame photometry) and potassium permanganate (absorption photometry). The student examines the content of iron and copper ions by spectrophotometric titration with EDTA. The student determines the content of weak and strong acids by pehametric and conductometric titration. The student determines the content of fluorides using the potentiometric method, electrolytically separates metallic copper and lead (IV) oxide and determines their mass by weighing the electrodes before and after the reaction, detects and determines the quantitative content of lead ions by analyzing the potentials and currents of redox peaks (KP6_UW2).

• The student is able to operate a flame photometer, UV-Vis spectrophotometer, pH meter, potentiometer, conductometer, potentiostat, and electrolyzer (KP6_UW3).

• The student uses spreadsheets, e.g., MS Office Excel, to analyze experimental data, e.g., to draw a reference curve or determine the first and second derivatives (KP6_UW6).

COMPETENCIES:

• The student understands the need to systematically familiarize themselves with basic sources of chemical information (journals, patents, books, databases) and to critically use artificial intelligence tools in relation to the interpretation of results obtained by spectroscopic and electroanalytical methods (KP6_KK1).

• The student is ready to critically assess the reliability of the interpretation of the data obtained by referring to literature data (KP6_KR2).
