Introduction

The aim of the course is to provide the students with fundamental knowledge in chemistry.

Innhold

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.

Læringsutbytte

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.

Bruk av KI som studiestøtte i studiearbeidet

AI tools may be used in KJE155 as a learning aid, but must never substitute for the chemistry understanding the course builds — classifying reactions and doing calculations on equilibrium, acid-base and electrochemistry yourself is precisely what you must master yourself. Productive uses include asking AI to explain a concept (e.g., how a buffer resists pH change, what drives a redox reaction, or how solubility is calculated), to check the setup of a problem you have solved yourself, or to generate practice problems for self-testing before the exam. You remain responsible for critically evaluating whatever the AI produces, and any use of AI in assessed work must follow the course's guidelines.

Course assessment

The faculty decides whether early dialogue will be held in all courses or in selected groups of courses. The aim is to collect student feedback for improvements during the semester. In addition, a digital course evaluation must be conducted at least every three years to gather students’ experiences.
