Lowry Bronsted theory definition of acids and bases
An acid is a proton donor. A base is a proton acceptor.
Hydrolysis
The reaction of a salt with water
Equivalence point of a titration
The point at which the acid has completely reacted with the base.
Endpoint of titration
The point where the indicator change colour
Strong acids
Acids which ionise completely in water to for high concentration of H3O+ ions.
Weak acids
Acids which ionise incompletely in water to form a low concentration of H3O+ ions
