Acids, Bases & Salts Flashcards
1
Q
what type of reaction makes water?
A
neutralisation reactions
2
Q
what does MASH stand for?
A
Metal + Acid —> Salt + Hydrogen
3
Q
what is a use of salt?
A
fertilisers
4
Q
tell me about acids
A
- produce H+ ions in aqueous solution
- strong acids fully dissociate in water
- weak acids partially dissociate in water
5
Q
tell me about bases
A
- react with acids to produce salt & water
- generally metal oxides & hydroxides
6
Q
tell me about alkalis
A
- bases that are soluble in water
- produce OH- ions in aqueous solution
- strong alkalis fully dissociate in water
- weak alkalis partially dissociate in water
7

A
proton donor
8
Q
what is a base?
A
proton accepter
9
Q
what is a salt?
A
a compound where the ionisable H+ ions of an acid are replaced by other cations (positive ions)
10
Q
what is water of crystallisation?
A
molecules of water locked in the ionic lattice
11
Q
what does hydrated mean?
A
contains water of crystallisation
12
Q
what does anhydrous mean?
A
does not contain water of crystallisation
