These atoms form small groups called molecules. In water, for example, each molecule is made up of two hydrogen atoms and one oxygen atom. The formula for a molecule of water is H2O. "H" means hydrogen, "2" means 2 hydrogen atoms, and the "O" means oxygen. Acids and Bases When an acid is poured into water, it gives up H (hydrogen) to the water. When a base is poured into water, it gives up OH (hydroxide) to the water. Stronger acids give up more protons (the positively charged parts of atoms); stronger bases give up more OH- (hydroxide). Neutral substances have an even balance of protons and OH-. pH Levels of Different Substances BASE 14.0 Sodium Hydroxide 13.0 Lye 12.4 Lime (Calcium hydroxide) 11.0 Ammonia 10.5 Milk of Magnesia 8.3 Baking Soda 7.4 Human Blood NEUTRAL 7.0 Pure Water ACID 6.6 Milk 4.5 Tomatoes 4.0 Wine & Beer 3.0 Apples 2.2 Vinegar 2.0 Lemon Juice 1.0 Battery Acid 0.0 Hydrochloric Acid |
