3. Two tankers accidentally dropped 656 gallons of a 2.25M barium nitrate solution and 425 gallons of a 1.75M aluminum nitrate solution into a holding pond at a chemical plant. The manager of the plant instructs you to determine what can be used and how much to precipitate out all the barium ions and none of the aluminum ions. You have a variety of 3M sodium salt solutions( NaNO3, NaCl, NaOH, Na2SO4, Na3PO4, Na2CO3, Na2CrO4) to use.

a. Which sodium salt solutions will you use? Explain.




b. Write the balanced molecular equation for the reaction that will take place.



c. Write the net ionic equation for the reaction that will take place.



d. Calculate how much( in gallons) of the sodium salt solution will be used for this reaction. Show all work.




e. Calculate the mass( in pounds) of precipitate that will form. Show all work.
