In the Electrolysis unit, pupils will build on their understanding of chemical reactions to explore the process of electrolysis and its applications.

In the Acids and Bases unit, pupils learned about the properties of acids, bases, and alkalis, and the reactions between them to form salts and water.

This unit explores empirical formulae, balanced chemical and ionic equations, gas identification, acid reactions, and pH as a measure of hydrogen ion concentration. It covers separation techniques and focuses on planning experiments, accurate measurements, safety, and communicating findings.

Making salts

What does the subscript number 4 in H$$_2$$SO$$_4$$ represent?

5Al$$_2$$(SO$$_4$$)$$_3$$ is written down as part of a balanced chemical equation. Which number is the coefficient?

Potassium iodide can be represented as KI$$_{(aq)}$$ in a chemical equation. What does $$_{(aq)}$$ tell us about the potassium iodide?

In a solution there may be several types of ions, of which some react together and others do not. What is the name of the ions that stay in solution and do not react? 

barium chloride + sodium sulfate → barium sulfate + sodium chloride

BaCl₂ (aq) + Na₂SO₄ (aq) → BaSO₄ (s) + 2NaCl (aq)

Ba²⁺(aq)+2Cl⁻(aq)+2Na⁺(aq)+SO₄²⁻(aq) → Ba²⁺(aq)+SO₄²⁻(aq)+2Na⁺(aq)+2Cl⁻(aq)

Ba²⁺ (aq) + SO₄²⁻ (aq) → BaSO₄ (s)

What is the correct ionic equation for the formation of barium sulfate?
