An acid is a substance that donates protons (H+) when dissolved in water. A base is a substance that accepts protons when dissolved in water. A salt is a neutral compound formed from the reaction of an acid and a base. The pH of an acid is less than 7, the pH of a base is greater than 7, and the pH of a salt is neutral at 7. For example, hydrochloric acid (HCl) is an acid, sodium hydroxide (NaOH) is a base, and the salt formed from their reaction is sodium chloride (NaCl).
