Slide 2 pH: a measure of the acidity or basicity of an aqueous solution The measure of hydrogen ions (these are positively charged) Slide 3 A solution is acidic if the pH is less than 7 A solution is basic if the pH is more than 7 Slide 4 pH scale- measures how acidic, basic, or neutral a substance is Ranges from 0-14 pH of 7= neutral pH of less than 7= acidic pH of more than 7= basic Slide 5 Basic Slide 6 Pure water is neutral (pH=7) When chemicals are mixed with water, the mixture can be acidic or basic The pH of a sample of water determines its health and solubility Slide 7 Ex: vinegar and lemon juice High concentration of H ions Become more acidic when added to water Slide 8 Ex: ammonia and baking soda Low concentration of H ions Concentration of H ions is reduced when added to water Slide 9 1) Ammonia 2) Distilled water 3) Hydrochloric acid 4) Lemon juice 5) Milk 6) Rubbing alcohol 7) Soda 8) Sodium Hydroxide 9) Vinegar Slide 10
