50 mL of 0.10 M is mixed with 50 mL of 0.060 M (volumes additive; , ). Treat AgCl as completely insoluble. Which statements are correct?

  1. AThe final is 0.010 M
  2. BThe final is 0.060 M
  3. CThe mass of AgCl precipitated is 0.7175 g
  4. DThe final is 0.050 M

Answer: A, C, D

= 5.0 mmol; = 2 x 3.0 = 6.0 mmol, so Ag+ is limiting and AgCl = 5.0 mmol = 0.7175 g (true). Cl- left = 1.0 mmol in 100 mL = 0.010 M (true). Ba2+ = 3.0 mmol in 100 mL = 0.030 M, so 0.060 is false (false). Nitrate = 5.0 mmol in 100 mL = 0.050 M (true).
