Neutralizing Acids
You must use an alkali of the same strength
pH
Power of Hydrogen
1-6 = Acids
8-14 = alkalis
7= neutral
1= very strong acid
14 = very strong alkali
Real life examples
12.5 = bleach
2.4 = lemon juice
Pure water = 7
skin= 5.5
soap = 9-10
Equations for the reactions of acids
Acid + Metal oxide --> Salt + Water
Acid + metal hydroxide --> Salt + water
Metal + acid --> salt + hydrogen
Acid + Metal carbonate --> Salt + water + Carbon Dioxide
Acid + Alkali --> Salt + water
Acid + Metal Hydrogen Carbonate --> Salt + Water + Carbon Dioxide
Making Salts
Naming Salts
The name of a salt has two parts
The first part comes from the metal in the base used
The second part comes from the acid that was used
e.g Write a word equation for copper sulphate
Copper oxide + Sulphuric acid --> Copper sulphate + Water
Copper carbonate + sulphuric acid --> Copper sulphate + water + carbon dioxide
