Chemistry 1
Language and models in chemistry
The aims of the training are to enable the apprentice to- give an account of the historical development of the concept of the atom and describe and compare Bohr’s atomic model and today’s model
- explain, illustrate and evaluate the composition, valency and properties of matter using the periodic table
- give names to simple inorganic compounds using nomenclature rules
- write chemical equations with state symbols, and use chemical equations in calculations with amounts of matter
- explain the concepts entropy and enthalpy and use them to assess whether or not a reaction is spontaneous
- give an account of conditions that affect the rate of chemical reactions
- carry out calculations on chemical equilibriums and discuss the equilibriums
Methods and experimentation
The aims of the training are to enable the apprentice to- plan and carry out experiments and evaluate risk, sources of error and results
- write reports from experiments and present processes, methods and results with or without digital tools
- discuss and evaluate the chemical content in media reports and advertisements
Water chemistry
The aims of the training are to enable the apprentice to- give an account of the properties of water
- give an account of water as a solvent for polar and non-polar substances
- evaluate the solubility and precipitation of salts in water based on experiments and calculations
- make aqueous solutions with different concentrations by weighing and diluting
- carry out experiments with water treatment and give an account of the contamination of drinking water sources
- explain how the key components in detergents work
Acids and bases
The aims of the training are to enable the apprentice to- define the terms acid and base and give an account of acid-base reactions
- calculate values of Ka, Kb and Kw
- measure pH by different methods and calculate pH in strong and weak acids and bases
- plan and carry out acid-base titrations; justify choice of indicator and interpret titration curves
- give an account of protolysis of salts and gases in water
Organic chemistry 1
The aims of the training are to enable the apprentice to- give an account of the structure, nomenclature, production, properties and use of aliphatic hydrocarbons, alkyl halides, alcohols, aldehydes, ketones, carboxyl acids, esters, ethers and amines
- give an account of the structure of benzene and some simple benzene derivatives, and give examples of their uses
