d. Concentrated
4. Give an example of each of the following.
a.
A weak acid
b. A weak base
c. A strong acid

5. What is neutralization?
6. What are the products if equal amounts of an acid and a base react?
7. Is acid/base neutralization endothermic or exothermic?
8. Define and give two examples of polyprotic acids.
9. What is a titration?
10. What laboratory glassware is used in a titration?
11. What is true about the amount of H+ (acid) and OH- (base) in a solution at the equivalence point of a
titration?
12. How can we know that the endpoint in a titration has been reached?
13. In an acid/base neutralization, the cation of the base and the anion of the acid combine to make a salt.
What acid and base must have combined to make each of the following salts?
NaCl
NH4Cl
Na2SO4
K3PO4
KNO3
Ca(NO3)2
14. At the equivalence point, moles of acid in the solution = moles of base. For monoprotic acids and
bases, we can express this mathematically as
MaVa = MbVb
a. 38.0 mL of 0.10M HCl is needed to neutralize 25.0 mL to NH4OH. What is the molarity of the
ammonium hydroxide?
b. 29.5mL of 0.15M NaOH neutralizes 25.0mL of HNO3. What is the molarity of the acid?
c. 30.0mL of 0.20M HCl will be neutralized with 0.50M NaOH. What volume of the base is
needed?
