    Acid Base
    An acid is any chemical compound which when dissolved in water gives a solution with a hydrogen ion activity greater than in pure water. A base is an aqueous substance that can accept hydrogen ions.
    An acid is an substance which donates a proton. A base is any substance which accepts a proton.

    Acids free hydrogen ions (H+)
    when mixed with water.    		 Bases free hydroxide ions (OH-) when mixed with water.
    An acid has a chemical formula with H
    at the beginning of it.
    For example, HCl (Hydrochloric Acid).    		 A base has a chemical formula with OH at the end of it.
    For example, NaOH (Sodium Hydroxide).
