Chemical Calculations

The course comprises a theoretical module and a laboratory module. Learning outcome 9 only relates to the laboratory module, while the other components can be treated in either module. Learning outcome 1: numerical values, significant figures, converting units, unit analysis Learning outcome 2: the ideal gas equation, pressure, volume, temperature, amount of substance, the gas constant Learning outcome 3: empirical formula, molecular formula Learning outcome 4: chemical reactions in general, redox reactions in particular, molecular reaction equation, ionic reaction equation, net ionic reaction equation, limiting reagents, yield in chemical reactions, simple electrolysis problems, concentration, amount of substance, mass, molar mass Learning outcome 5: dynamic equilibrium, activity, activities at equilibrium, concentrations at equilibrium, the acid constant (Ka), the base constant (Kb), conjugated acid-base pair, solubility product (Ksp), solubility, complex constant, equilibrium constant (concentration, Kc and pressure, Kp), reaction quotient, Le Châtelier's principle, common reactant, the autoionisation of water, pKa, pKb, pKw Learning outcome 6: pH, pOH, pH indicators, pH calculations, buffer solutions, buffer equation (Henderson-Hasselbalch), preparation of buffer solutions Learning outcome 7: concentration, amount of substance, mass, molar mass, calculate the dilution of solutions, redox titration, acid-base titration Learning outcome 8: kinetics, the rate of a reaction, rate constant, half-life, the Arrhenius equation, activation energy Learning outcome 9: practical laboratory work based on theory treated in the course, laboratory safety, and results from the laboratory work reported according to instructions.
