Reactions of acids
1 Indicators
1.1 Universal Indicator
1.1.1 Strong Alkalis
1.1.2 Neutral
1.1.3 Strong Acids
1.1.4 Inbetween
1.1.5 Inbetween
1.2 Litmus
1.2.1 Alkalis
1.2.2 Acids
1.2.3 Neutral
2 Neutralizing Acids
2.1 You must use an alkali of the same strength
3 pH
3.1 Power of Hydrogen
3.2 1-6 = Acids
3.3 8-14 = alkalis
3.4 7= neutral
3.5 1= very strong acid
3.6 14 = very strong alkali
3.7 Real life examples
3.7.1 12.5 = bleach
3.7.2 2.4 = lemon juice
3.7.3 Pure water = 7
3.7.4 skin= 5.5
3.7.5 soap = 9-10
4 Equations for the reactions of acids
4.1 Acid + Metal oxide --> Salt + Water
4.2 Acid + metal hydroxide --> Salt + water
4.3 Metal + acid --> salt + hydrogen
4.4 Acid + Metal carbonate --> Salt + water + Carbon Dioxide
4.5 Acid + Alkali --> Salt + water
4.6 Acid + Metal Hydrogen Carbonate --> Salt + Water + Carbon Dioxide
5 Making Salts
5.1 Naming Salts
5.1.1 The name of a salt has two parts
5.1.1.1 The first part comes from the metal in the base used
5.1.1.2 The second part comes from the acid that was used
5.1.2 e.g Write a word equation for copper sulphate
5.1.2.1 Copper oxide + Sulphuric acid --> Copper sulphate + Water
5.1.2.2 Copper carbonate + sulphuric acid --> Copper sulphate + water + carbon dioxide
