When an aqueous solution of strontium chloride is added to an
aqueous solution of potassium sulfate, a precipitation reaction
occurs. Write the balanced net ionic equation of the reaction.
Silver sulfate solution is added to 25.00 mL of a 0.500 M potassium
chloride solution until no more precipitate forms. What mass of
silver chloride will be formed? What concentration of potassium
will remain in solution after the reaction is complete if 45 mL of
silver sulfate solution were added to the potassium chloride
solution?
Aqueous potassium phosphate is added to 545 mL of a solution
containing calcium chloride to precipitate all of the Ca2+ ions as
the insoluble phosphate (310.2 g/mol). If 4.51 g calcium phosphate
is produced, what is the Ca2+ concentration in the calcium chloride
solution in g/L?
2. Consider a 0.15 m strontium chloride aqueous solution.
a. Determine the molality (in m) of all solutes in the solution.
Assume that strontium chloride completely ionizes when dissolved in
water. All solutes means all cations and anions. The molality that
you determine here is the value for msolute of (Equation 3) in the
“Background and Procedure” file. You must explain your answer. No
credit will be given if you write only calculations. (Hint: See
Example 3 of the Background...
When an aqueous solution of 7.00 g of BaCl2 was added

The reaction of aqueous potassium chloride and aqueous lead(II)
nitrate produces lead(II) chloride and potassium nitrate, according
to the balanced chemical equation shown. 2 KCl (aq) + Pb(NO3)2 (aq)
→ PbCl2 (s) + 2 KNO3 (aq) If equal volumes of 0.500 M KCl (aq) and
0.500 M Pb(NO3)2 (aq) are combined, what will the final
concentration of KNO3 (aq) be?
Suppose 0.127g of zinc chloride is dissolved in 50.mL of a
23.0mM aqueous solution of potassium carbonate. Calculate the final
molarity of zinc cation in the solution. You can assume the volume
of the solution doesn't change when the zinc chloride is dissolved
in it. Be sure your answer has the correct number of significant
digits.

molarity of chloride anion in the solution. You can assume the
volume of the solution doesn't change when the potassium chloride
is dissolved in it. Round your answer to 3 significant digits.
