Question 1

0.10 M potassium chromate is slowly added to a solution containing 0.20 M AgNO3 and 0.20 M Ba(NO3)2. What is the Ag+ concentration when BaCrO4 just starts to precipitate? Ksp for Ag2CrO4 and BaCrO4 are 1.1 × 10-12 and 1.2 × 10-10, respectively.
◦ 4.3 × 10-2 M
◦ 6.5 × 10-5 M
◦ 1.3 × 10-4 M
◦ 3.2 × 10-4 M
