 What just happened with the witches and their pink potion?

 Chemicals that respond to a change in H ion concentration  Change color depending on whether substance is an acid or a base  Examples:  litmus paper  phenolphthalein

 What is an ion?  Answer: positively or negatively charged atom

 A compound that forms H + ions in a solution  Example: Hydrochloric acid produced by stomach to digest food (HCl)

 Contains Hydrogen (H+)  Turns litmus paper red  Tastes sour  Dissolves metal

 A compound that forms hydroxide ions (OH-) in a solution  Example: Lye

 Contains Hydroxide  Turns litmus paper blue  Tastes bitter  Feels slippery

 The pH scale  What does pH stand for  Power of Hydrogen  Scale ranges from 0 to 14

 Acids have a pH below 7  Strong acids range from 1 to 3  Strong acid example: HCl

 Bases have a pH above 7  Strong bases range from 11 to 14  Strong base example: lye

 pH increases tenfold

 A water molecule can react to form ions

 Why is pure water considered “neutral”?  Pure water pH = 7  Number of positive hydrogen ions equal to negative hydroxide ions produced
