This describes a reaction using a symbol equation with coefficients which ensure there are equal numbers of atoms of each element on both sides of the symbol equation.

These are used in chemical equations to indicate the physical state of a substance.

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 are the products of a reaction between a metal carbonate and an acid?

bubbling through limewater turns it cloudy white

Which compounds have the correct chemical formulae for carbonates?

What is the chemical formula for the metal salt formed when strontium carbonate (SrCO₃) and hydrochloric acid (HCl) react together?

carbon dioxide + limewater → calcium bicarbonate + water

carbon dioxide + limewater → calcium carbonate + water

carbon dioxide + limewater → calcium carbonate + oxygen

What is the correct word equation for the test for carbon dioxide gas?

CO₂ + Ca(HCO₃)₂ → CaCO₃ + H₂O

What is the correct symbol equation for the test for carbon dioxide gas?

What is the general reaction of an acid with a metal?

Which ion is found in alkaline solutions?

A base is a solid and an alkali is a liquid.

An alkali is a base that dissolves in water.

What is the difference between a base and an alkali?

What is the product when an acid reacts with a base?
