Learning outcomes Success criteriaUnderstand what bases are. State the definition for a base.
Name the three types of base.
Given its name, you can classify a substance as a base or not.
Understand the relationship between bases and alkalis.
Given the name of a chemical and information about its solubility, you can state whether or not it can form an alkali.
Bases
• A base is a substance which reacts with an acid to produce water.
• The three types of base are:– metal oxides– metal hydroxides– metal carbonates

Neutralisation
S2 ChemistryClassifying chemicals and chemical reactions
Learning outcomes Success criteriaUnderstand what a neutralisation reaction is.
Define the term “neutralisation reaction”.
Given information about the reactants, you can state whether or not a neutralisation reaction will occur.
Describe what happens to the pH of an acid or alkali in a
neutralisation reaction.
Know everyday examples of neutralisation reactions.
Describe at least three everyday examples of neutralisation reactions, including details of:
– the acid and base involved– the beneficial effect that is produced
Neutralisation is the reaction of acids with
• Metal ,
A base that dissolves in water forms an .
Neutralisation:• moves the pH of an acid .• moves the pH of an alkali .
