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