Module 3 | Water

Focus 3: Water is an important solvent

Lesson 1 | Solubility in water

  • Explain changes, if any, to particles and account for those changes when the following types of chemicals interact with water:
    – a soluble ionic compound such as sodium chloride
    – a soluble molecular compound such as sucrose
    – a soluble or partially soluble molecular element or compound such as iodine, oxygen or hydrogen chloride
    – a covalent network structure substance such as silicon dioxide
    – a substance with large molecules, such as cellulose or polyethylene

  • Analyse the relationship between the solubility of substances in water and the polar nature of the water molecule.

  • Process information from secondary sources to visualise the dissolution in water of various types of substances and solve problems by using models to show the changes that occur in particle arrangement as dissolution occurs.

Lesson 2 | Investigating solubility

  • Perform a first-hand investigation to test the solubilities in water of a range of substances that include ionic, soluble molecular, insoluble molecular, covalent networks and large molecules.
