Content

The course includes reactions in aqueous solutions (redox, precipitation, and neutralization reactions), thermodynamics, acids and bases, properties of solutions (solubility and osmosis), acid-base titrations, factors that affect solubility, buffers, chemical kinetics and electrochemistry.

Learning outcome

On completion of the General Chemistry w/o laboratory exercises, the students should be able to:

  • classify reactions in aqueous solution into neutralization reactions, precipitation reactions, and redox reactions.
  • define enthalpy change and explain how it can be measured in a coffee-cup calorimeter and how we apply the first law of thermodynamics in such measurements.
  • explain when a reaction has reached its chemical equilibrium and recognize the role of chemical equilibrium in the La Châtelier’s principle.
  • explain the difference between a spontaneous and nonspontaneous reaction and how to use the reaction free energy or the reaction quotient to decide whether a reaction occurs spontaneously or not.
  • define change in entropy and recognize how it is used in the second law of thermodynamics to decide whether a process is spontaneous or nonspontaneous.
  • define a solution and recognize the parameters that affect the solubility of a solute in a solvent.
  • define osmosis and explain the role of entropy change in such physical property of a solution.
  • describe the difference between a galvanic cell and electrolytic cell and explain the role of redox reactions in such cells.
  • use the Nernst equation to calculate the cell potential.
  • explain the corrosion process and give examples of how to protect objects from corrosion.
  • define a base and acid by using the Brønsted-Lowry and Arrhenius acid-base theory, respectively, and to define pH. The students will be able to employ the acid and base definitions to calculate the pH of a solution.
  • define a buffer and being able to explain why its pH changes only little when a small amount of strong acid or base is added.
  • give examples of parameters that affect the rate of a reaction.
  • explain the difference between first and second order reactions.
