Question- 0.10 M potassium chromate is slowly added to a solution containing 0.50 M AgNO3and 0.5 M Ba(NO3)2. What is the Ag+ concentration when BaCrO4 just starts to precipitate? The Ksp for Ag2CrO4 and BaCrO4 are 1.1x10-12 and 1.2x10-10, respectively.
This is the question for that you have to provide expert solution
