Silver Nitrate Day Five Lab

OBJECTIVE

• Predict the mass of a product,
• and calculate percent yield.

INFO

• AgNO₃ + NaCl --> AgCl_(S) + NaNO₃
• AgNO₃ = 169.872 g/mol
• Ag = 107.868 g/mol
• Cl = 35.452 g/mol

Mass out to thousandths (3 decimal places)

DATA

9. mass of Beaker A with AgNO₃ = g
10. mass of filter paper = g
11. mass of Beaker A, filter paper & AgCl = g

PROCEDURE

1. Mass out Beaker A with the AgNO₃.
2. Pour 75 mL distilled water into Beaker A and stir to dissolve the AgNO₃.
3. Pour 75 mL saturated NaCl solution into Beaker B.
4. Pour Beaker B (NaCl) into Beaker A (AgNO₃).
5. Place Beaker A on hotplate and set on high.

*** Back to Seats ***

6. Heat Beaker A, the AgCl_(S) and NaNO₃ solution, until it boils.
7. Decant the NaNO₃ solution (it's CLEAR) through a funnel and filter paper, and pour down the drain.
1. SAVE THE WHITE STUFF (AgCl_(S))
2. Don't poke a hole in filter paper!
8. Place the filter paper into Beaker A with the white AgCl_(S) and put in the fume hood.
9. Wash with soap Beaker B, the glass stirring rod, and the funnel, and dry. Return trays.

*** Part Two ***

10. Mass out Beaker A, filter paper, and AgCl_(S).
11. Scrape AgCl into bag and bucket.
12. Wash with soap, and dry Beaker A.
13. Enter data: silver_nitrate_day_5
14. Due at the end of the period.

For all calculations:

• have at least one blank line between each
• have them properly numbered
• show all work

CALCULATIONS

1. molar mass of AgCl = g/mol
2. mass of AgNO₃ = g
3. actual mass of AgCl = g
4. theoretical mass of AgCl = g
5. percent yield of AgCl = %
