Section 11.1 – Acids and Bases Goal: Describe and name acids and bases. Summary: An Arrhenius acid produces H+ and an Arrhenius base produces OH-in aqueous solutions. Acids taste sour, may sting, and neutralize bases. Bases taste bitter, feel slippery, and neutralize acids. Naming acids: Binary acids contain a single anion: H n X. To name:
