OCR GCSE Chemistry Neutralisation reactions
This page covers the following topics:
1. Neutralisation reactions
2. Soluble salts
3. Neutralisation equations
A neutralisation reaction occurs between an acid and a base, producing neutral water and a neutral salt. The product solution will have a neutral pH (6-8) which can be detected with a pH indicator.
There are two ways to make and isolate soluble salts. First, you can react an acid with a soluble base, forming a salt in solution which can be isolated by evaporation. Or, you can react an acid with an insoluble base, also forming a salt in soltuion. But, you must first filter off any remaining insoluble base, before evaporating the filtrate to isolate the salt.
Neutralisation equations are the chemical reaction equations for neutralisation reactions between an acid and a base to produce a salt and water.
An acid solution is a source of what ion?
A base in solution is a source of which type of ion?
Describe the process of forming and isolating a soluble salt, using an insoluble base.
What are the two products of a neutralisation reaction?
