A substance that produces H+(aq) ions in aqueous solution. Strong acids ionize completely or almost completely in dilute aqueous solution. Weak acids ionize only slightly. Chemicals or substances having the property of an acid are said to be acidic.

Acids taste sour, turn litmus red, gives a solution with a pH of less than 7 when dissolved in water and often react with some metals to produce hydrogen gas.
