Multiple Choice

Identify the true statement about the following reaction:

F^- + H₂O --> HF +OH^-

• H₂O is a bronsted lowry base

• H₂O is not an acid or base according to either model

• H₂O is a bronsted lowry acid

Multiple Choice

• H₂SO₄, SO₄^2-

• OH^-, H₂O

• NH₄⁺, H₂O

• H₂CO₃, HCO₃^-

Multiple Choice

Could C₂H₃O₂^- act as a base when placed in water?

• Yes, because it can accept a H⁺

• Yes, because it can donate a H⁺

• No, because it cannot donate a H⁺

• No, because it cannot accept a H⁺
