                • yep, it's true
                1. Hydrochloric Acid (HCl)
                  1. Sulphuric Acid
                    1. Turns blue litmus red
                      1. Red in methyll orange
                    2. Bases
                      1. Mild Bases: Soap, Toothpaste
                        1. Sodium Hydroxide (NaOH) caustic soda
                          1. Alkali is a base soluble in water.
                            1. Turns red litmus blue
                              1. Yellow in methyll orange
                              2. <7 on pH scale
                                1. Strong = corrosive!
                                2. Indicators
                                  1. Is a substance which tells you by means of a colour change, whether a substance is an acid or a base.
                                    1. Methyll Orange
                                      1. Universal Indicator
                                      2. Litmus
                                      3. Titration
                                        1. Methyll Orange Indicator
                                          1. Acid on top in burette, Base on bottom in conical flask
                                            1. Hydrochloric Acid + Sodium Hydroxide = Sodium Chloride + Water
