air."
Answer NH4+ - NH3 and H2O - OH-
7. Conjugate Acids and Bases
, Answer The term conjugate means "joined together as a p Reactions between acids
and bases always yield their conjugate bases and acids.
8. REVIEW ARRHENIUS ACIDS AND BASES
Answer An acid is a substance that, when dissolved in water, increases the concentration of hydrogen
ions.
A base is a substance that, when dissolved in water, increases the concentration of hydroxide ions.
