Question 19
0/2 pts 3
Details
You have a mixture of sodium chloride (NaCl) and potassium chloride (KCl) dissolved in water
and want to separate out the Cl- ions by precipitating them out using silver ions (Ag+). The
chemical equation for the net ionic reaction of NaCl and KCl with silver nitrate, AgNO3, is shown
below.
Ag+(aq) + Cl(aq) → AgCl(s)
The total mass of the NaCl/KCl mixture is 1.299 g. Adding 50.42 mL of 0.381 M solution
precipitates out all of the Cl-.
What are the masses of NaCl and KCl in the mixture?
Atomic masses:
g: Mass of NaCl
g: Mass of KCL
Ag = 107.868 g
