An acid (from the __[|Latin]__ acidus/acēre meaning sour) in common usage is a substance that tastes sour, reacts with metals and carbonates, turns blue litmus paper red, and has a [|pH] less than 7.0 in its [|standard state]. Examples include [|acetic acid] (in [|vinegar]) and [|sulfuric acid] (used in [|car batteries]). Acid/base reactions differ from [|redox] reactions in that there is no change in [|oxidation state]. Acids can occur in solid, liquid or gaseous form, depending on the temperature. They can exist as pure substances or in solution. Chemicals or substances having the property of an acid are said to be acidic.
