Atom economy
A measure of the amount of reactant converted to a useful product.
2 of 19
Avogadro constant
The number of particles one mole of any substance - 6.02 times 10 to the 23
3 of 19
Concentration
The amount of substance in a given volume, normally measured in units of mol/dm3.

Half equation
Used to show what happens to one of the reactants in a chemical reaction.
6 of 19
Hydration
A reaction in which H20 is added to a substance.
7 of 19
Indicator
A chemical that is one colour in an acid and another colour in an alkali.
8 of 19
Ionic equation
A simplified version of a chemical equation, which just shows the species that are involved in the reaction.
9 of 19
Limiting reactant
The reactant that is completely used up in a reaction; it stops the reaction from going any further and any further products being produced.

Mole (mol)
The unit for measuring the amount of substance; one mole of any substance contains the same number of particles; the mass of one mole of a substance is equal to the relative formula mass in grams.
11 of 19
Oxidation
When a species loses electrons.
12 of 19
Percentage yield
A calculation used to compare the actual yield of a product obtained from a reaction with the maximum theoretical yield.
13 of 19
Relative atomic mass (Ar)
The ratio of the average mass per atom of the element to one-twelfth the mass of an atom of carbon-12.
14 of 19
Relative formula mass (Mr)
The sum of the relative atomic masses of all the atoms shown in the formula.
15 of 19
Solute
A substance that dissolves in a solvent to form a mixture called a solution.
16 of 19
Species
The different atoms, molecules or ions that are involved in a reaction.
17 of 19
Sustainable development
Development that meets the needs of the current generation without compromising the ability of future generations to meet their own needs.
18 of 19
Titration
An accurate technique that can be used to find out how much of an acid is needed to neutralise an alkali.
