acids and bases

Acid according to Arrhenius

Acids produce hydrogen ions in aqueous solutions

acids according to Lowry-Bronsted theory

An acid is a proton donator

Bases according to Arrhenius’ theory

Produces hydroxide ions in aqueous solutions

Bases according to the Bronsted Lowry theory

A proton acceptor

Strong acids

Ionize completely in water to form a high concentration of H3O plus ions

weak acids

Ionize in completely in water to form a low concentration of H3O plus ions

Strong bases

Dissociate completely in water to form a high concentration OH minus ions

Weak bases

Dissociate/ionize in completely in water to form a low concentration of OH minus ions

Hydrolysis

A reaction of a salt with water.

Approximate pH

(Equal two, smaller than or larger than seven) of salts insult hydrolysis

Hydrolysis of a weak acid and a strong base

Results in an alkaline solution pH less than seven examples include salts, such as sodium ethanoate , sodium oxalate, sodium carbonate

Endpoint point of a titration

The point where the indicator changes colour

Equivalence Point

Titration as the point at which the acid/base has completely reacted with the acid/base

Kw

The equilibrium constant for the ionization of water

Auto ionization of water

The reaction of water with itself to form H3O plus ions and OH minus ions
