Introduction to the chemistry of acids and bases. Acid molecules have an "H" group (one hydrogen atom) and can be sour. Bases have an "OH" group (an oxygen and a hydrogen atom) and can be slippery. "H" and "OH" groups give acids and bases different properties. 24 pp. Colorful illustrations. Reading Level 1-3, Interest Level 2-5.
