A type of base that dissolves in water forming hydroxide ions
A term used to describe a solution containing hydroxide ions
Alkaline earth metals
Group 2 metals.
Metals that don't occur in their elemental form naturally. They're found in stable compounds e.g. calcium carbonate for Ca
A measure of the concentration of hydroxide ions present in an alkaline solution
Units = moldm-3
A measure of the concentration of H+ ions present in a solution
A measure of the ability of a solute to dissolve in a solvent.
Often expressed in moldm-3. This represents the maximum number of moles of a solute able to dissolve in 1dm3 of water.
A negatively charged ion with more electrons than protons
A compound that neutralisaes an acid to form a salt
A positively charged ion with fewer electrons than protons
A redox reaction in which the same element is both oxidised and reduced
An attractive force between molecules.
Intermolecular forces can be london forces, permanent dipole-dipole interactions or hydrogen bonding.
Loss of electrons or an increase in oxidation number
Gain of electrons or a decrease in oxidation number
A reaction involving reduction and oxidation
