Acid and Base Reactions are based on the concentrations of both the hydronium ion (H₃O⁺) and the hydroxide ion (OH^-) in aqueous solutions. High concentrations of either ion gives otherwise dissimilar substances common properties and characteristics. This phenomenon is evident in everyday life. High H⁺ concentrations (H⁺ and H₃O⁺ are the same ion) cause soda pop to corrode our teeth and give certain foods a sour taste. Bases, with their high concentrations of OH^- ions, are often found in foods and household products such as bleach, vinegar, and antacids. Bases are usually slippery in texture and bitter to taste. With the variety that these two types of substances appear in life, it's a good idea to know a little bit about them and how they interact.
