II. Problems
1. Use the solubility chart below to answer the following:
a. Put in order from least to most soluble at 10oC: NH3, KClO3, NaCl, KNO3
b. Put the above compounds in order from least to most soluble at 90oC.
c. What is the solubility of NH4Cl at 60oC?

(NaHCO3) in 0.600 L of water?
4. If you begin with 100.0 mL of a 3.00 M HCl solution and you dilute it with water to
50θ mL, what will the new concentration be?
5. What volume of concentrated (12 M) HCl do you need to make 50θ mL of a 1.00 M
6. How many mL of water are needed to dilute 5.0 mL of concentrated HCl (12 M) into
a 3.0 M solution?
7. How many grams of sodium chloride (NaCl) are needed to make 50θ mL of a 2.00 M
