Chemistry
Acids and bases are common chemicals. Acids release H+ ions when in water, and bases release OH− ions when in water. Acids can react with bases. The H+ ion is taken from the acid by the base. This makes water, H2O. A salt is also made when an acid and a base react together. An example would be reacting hydrochloric acid (HCl) and sodium hydroxide (NaOH). Hydrochloric acid releases H+ and Cl- ions in water. The base releases Na+ and OH- ions. The H+ and the OH- react to make water. There is a solution of sodium chloride (NaCl) left. Sodium chloride is a salt.
