4. Aluminum hydroxide, one of the antacid ingredients in Maalox, can pe prepared by the
reaction of aluminum sulfate and sodium hydroxide. How many milliliters of 0.200 M
NaOH solution are needed to completely react with 3.50 g of aluminum sulfate?
a. Write a balanced chemical equation for the double replacement reaction.
Show all physical states. (remember that your compounds need to be neutral
BEFORE balancing or else it will not work).
b. How many moles of NaOH are needed to react with 3.50g of Aluminum Sulfate?
c. If the solution of NaOH is 0.200M, determine how many mL is needed based on
your mole amounts in part b.
5. Chalk is composed of calcium carbonate. This water-insoluble compound is formed
when a solution of calcium chloride is added to a solution of sodium carbonate. What
volume (in mL) of 0.550M calcium chloride is required to completely with 750.0 mL of
0.250 M sodium carbonate solution? (You will need to show all steps in this problem.)
