what is an acid?
what is the basicity of an acid?
number of hydrogen ions which can be produced by one molecule of the acid upon ionisation
what is a salt?
ionic compound formed when a metal or ammonium ion replaces one or more hydrogen ion(s) of an acid
what is a metal carbonate?
ionic compound containing metal ion and carbonate ion
what is a base?
any metal oxide/hydroxide that react with acids to produce salt and water only (neutralisation)

soluble base that produces hydroxide ions in aqueous solution
what is the concentration of a solution?
amount of solute dissolved in 1dm^3 of solution
what are ammonium salts?
salts that contain ammonium ions
what is a saturated solution?
solution formed when the maximum amount of solute dissolves in a fixed volume of a solvent at a fixed temperature
what is a concentrated solution?
when a large number of particles of a substance is present in a fixed volume of solvent
what is a diluted solution?
when a small number of particles of a substance is present in a fixed volume of solvent
what is the strength of an acid/alkali?
the extent it ionises to produce H+ or OH- ions when dissolved in water
what is a strong acid/alkali?
an acid/alkali that ionises completely in an aqueous solution
