Solutions and Solubility

What this unit covers

The resources here follow the topic from the first definitions to the harder ideas. Early material explains that a solute dissolves in a solvent to form a solution. The notes titled Solutions, Concentration and Limestone make the point that there is a limit to how much solute can dissolve. The Dissolving mind map sets out soluble and insoluble substances in the same plain way.

Where to start

If the vocabulary is new, begin with the Solubility Cards flashcards, which cover solute, solvent, saturated, suspension and more. Then open the Solubility mind map, which defines solubility as the grams of solute that dissolve in 100 g of solvent at a set temperature.

1. Learn the terms with Solubility Cards.
2. Read the Solubility mind map.
3. Try the quiz called Solutions and Dissolving.

Rules, salts and precipitates

Once the basics are secure, move to the Solubility Rules mind map. It sorts compounds into soluble and insoluble groups, such as all nitrates and most chlorides. The Soluble salts preparation mind map is a decision path: does the metal react with acid, is the base or carbonate soluble, and which method follows. The Aqueous Solutions mind map goes further into solubility product, predicting precipitation, and strong and weak acids and bases.

Colligative properties

For university-style work, the Colligative Properties Vocabulary flashcards cover Raoult's Law, boiling point elevation, freezing point depression and osmotic pressure. The Advanced Chemistry Unit 6 Solutions Vocab deck adds molarity and solution equilibrium.

Using quizzes and maps together

Read a mind map first, then take a quiz on the same idea. Wrong answers show which branch to revisit. Flashcards then help the terms stick. This unit sits in the Matter and Its Properties strand of Chemistry. Choose one map today and see how much you can recall.
