Acids and Bases Flashcards
1
Q
Acid
A
- a proton donor
2
Q
Base
A
- a proton acceptor
3
Q
ionisation
A
- the reaction of a molecular substance with water to produce ions
4
Q
strong acid
A
- an acid that ionises completely in an aqueous solution.
5
Q
weak acid
A
- an acid that ionises partially in an aqueous solution
6
Q
polyprotic acids
A
- being able to donate more than one proton
7
Q
dissociation
A
- the splitting of an ionic compound into its ions
8
Q
strong base
A
- a base that dissociates completely in an aqueous solution
9
Q
weak base
A
- a base that only dissociates/ionises partially in an aqueous solution
10
Q
weak base salts
A
- metal carbonates
- metal hydrogen carbonates
11
Q
amphoteric substance
A
- a substance that can act as either a base or an acid
12
Q
salt
A
- a substance in which the hydrogen of an acid has been replaced by a cation
13
Q
hydrolisis
A
- a reaction of a salt ion with water
14
Q
neutralisation / equivalence point
A
- the point where an acid and a base have reacted so neither is in excess
15
Q
standard solution
A
- a solution of known concentration that is unlikely to change for a period of time
