Acid Base Properties

According to Arrhenius acid-base theory, an acid is....

• an H+ acceptor

• a H+ donor

• a substance that produces H+ in water

• anything with an H+

HSO₄^-(aq)+H₂O(l)      →       H₃O⁺(aq)+SO₄^2-(aq)
Identify the Acid in the above reaction.

• HSO₄^-

• H₂O

• H₃O⁺

• SO₄^2-
