Is acidic acid a molecular compound?
If you mean acetic acid then yes.
A compound in chemistry is when there are two or more elements bonded together that can be separated to become different substances. A strong acidic compound would be HCl (Hydrochloric Acid). A weak acidic compound would be H2CO3, (Carbonic Acid). A strong acid is one which is virtually 100% ionised in solution. A weak acid is one that does not ionise fully when it is dissolved in water.
