Acid-Base Properties and Theories

According to which theory is a base a substance which produces OH- ions in water?

• Arrhenius
• Bronsted-Lowry
• Lewis

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+

What might happen if you mixed a strong acid with an equally strong base?

• You would see an explosive chemical reaction.
• The acid would destroy the base.
• The base would destroy the acid.
• You'd wind up with a pH-neutral substance.
