In Ahrrenius acid/base reaction the products are the same - a salt and water
- salt is formed from the cation of a base, and the anion of the acid
- the strengths of the parent acid and parent base are the determiners of the strength of the salt
- strong acid + strong base = neutral salt
- strong acid + weak base = acidic salt
- weak acid + strong base = basic salt
- weak acid + weak base = neutral salt
- the strongest parent runs the reaction
The Hydrogen Ion in Water
- the hydrogen ion is simply a proton (nucleus of a hydrogen atom without its valence electron)
- is water, clusters of hydrated hydrogen ions form
- the simplest cluster is hydronium (H3O)+
- H+ is the same is H3O+
Water as an Acid and a Base
Water can act as an acid because it can donate a proton. Water can be a base because it can accept a proton to form the hydronium ion.
