IONISATION is the reaction of a molecule substance with water to produce
ions
AN ELECTROLYTE is a substance that can conduct electricity by forming
free ions when molten or dissolved in solution
Monoprotic Acids provide one proton
Diprotic Acids provide two protons
Triprotic Acids provide three protons
DISSOCIATED is the splitting of an ionic compound into its ions
NEUTRALISATION is the point where an acid & a base have reacted so that
neither are in excess
A SALT is a substance in which the hydrogen of the acids has been replaced
by a cation
BRONSTED - LOWRY:

ACIDS ARE PROTON DONORS
BASES ARE PROTON ACCEPTORS
CONJUGATE ACIDS & BASES
When an acid donates a proton, it forms a conjugate base
half reaction
Hellag Ht l aa
acid base
, When a base accepts a proton, it forms a conjugate acid
half reaction
NH aq Ht NHa aq

PROTOLYTIC REACTIONS OR PROTOLYSIS
all acid base reactions
PROTOLYTIC REACTIONS is one in which protons are transferred
In protolytic reactions there are two conjugate acid-base pairs

An amphoteric substance can act as either an acid or a base
STRONG & WEAK ACIDS & BASES
Strong acids are fully ionised in aqueous solution
Weak acids are only partially ionised in aqueous solution
Strong bases are fully dissociated in aqueous solution
Weak bases are only partially ionised or dissociated in aqueous
