Acids + Bases Flashcards
Acid
A proton donor
Base
A proton acceptor
Strong Acids
An acid that ionises almost completely in an aqueous solution
- Sulfuric acid (H2SO4)
- Hydrochloric acid (HCl)
- Nitric acid (NHO3)
Ionisation
The reaction of a molecular substance with water to produce ions
Weak acids
An acid that only ionises partially in an aqueous solution
Strong bases
A base that dissociates almost completely in an aqueous solution
- Sodium hydroxide (NaOH)
- Potassium hydroxide (KOH)
- Lithium hydroxide (LiOH)
Dissociation
The splitting of an ionic compound into its ions
Weak bases
A base that only ionises partially in an aqueous solution
Amphoteric substance
A substance that can act as either a acid or base
Salt
A substance in which the hydrogen of a acid has been replaced by a cation
Hydrolysis
A reaction of an ion (from a salt) with water
Neutralisation
A chemical reaction in which an acid and a base react so that neither is in excess
Standard solution
A solution of known concentration
Kw for water
Kw = [H3O+][OH-]
