Acids
Substances with a pH of less than 7.
2 of 12
Bases
Oxides and hydroxides of metals with a pH greater than 7.
3 of 12
Alkalis
Soluble bases.

Both Bases.
5 of 12
Neutralisation
Acid + Base ---> Salt + Water
6 of 12
Where does the first name of a salt come from?
It comes from the name of the base or carbonate used. An example of this is: sodium hydroxide will make a sodium salt
7 of 12
Where does the second name of the salt come from?
It comes from the acid used, an example being: hyrdochloric acid will make a chloride salt or sulphuric acid will produce a sulphate salt.
