What is pH?
• pH measures the amount of H+’s in a solution– Water splits to form
ions– H+ and OH-

Acid
• <7 on pH scale• Higher concentration
of H+ in solution than OH-
• Properties– Sour taste– Ability to turn litmus
paper from blue to red– Proton donor
More acidic Less acidic

Basic/Alkaline
• >7 on pH scale
• More OH-, Less H+
• Properties– Slippery– Bitter– Proton recipient
Alkaline Less Alkaline

Neutral
• pH of 7
• Water!
• Balance of H+ and OH- ions

Interpreting the pH Scale
• Each decrease in number (more acidic) represents a 10x increase in the number of H+ ions

Testing pH
• Indicator: Chemical that changes color– Test to determine pH
• Litmus Test– Positive Acid Test: Turn blue litmus paper to
red– Positive Alkaline Test: Turn red litmus paper to
blue
• pH Paper– Changes color– Match color to key to determine the pH
