Answer each part using the chemical equation:
CaO + H2O -------------------> Ca2+ + 2 OH -
(The "2" in "Ca2+" is above the a in Ca)
A. Write the chemical formula for the reactant which gives up a hydrogen ion in this reaction.
B. Write the chemical formula for the reactant which accepts a hydrogen ion in this reaction.
C. Write the chemical formula for the reactant which behaves like an acid in this reaction.
D. Write the chemical formula for the reactant which behaves like a base in this reaction.
E. Is this aqueous solution an acid or a base? How do you know?
F. Would the pH of this solution be higher than 7 or lower than 7?
G. What does it mean to say that a chemical equation is reversible?
H. Rewrite the chemical equation to show that it is reversible
