pH scale

The pH is a measure of liquid acidity/alkalinity. It ranges from 0 to 14, where 0 is most acidic and 14 is most alkaline. The more acidic, the more hydrogen ions (h+) it contains. (1, 2, 3)

Examples of pH:

  • Battery acid = 0.3
  • Lemon juice = 2.2
  • Vinegar = 2.8
  • Gastric (stomach) acid = 1.5-3.6
  • Orange juice = 4.2
  • Milk = 6.7
  • Distilled water = 7 (perfectly neutral)
  • Blood = 7.4 (4)
  • Sea water = 8
  • Baking soda = 8.4
  • Ammonia = 11.5
  • Bleach = 12.6
