an aqueous solution of Na2CrO4 at 25 degrees C is added to an aqueous solution containing .001M Pb(NO3)2 and .001M Ba(NO3)2 at 25 degrees C. Which solid, if any, will precipitate first?
Homework Answers
Ksp of PbCrO4 = 3 x 10^-13
Ksp of BaCrO4 = 1.17 x 10^-10
Ksp of PbCrO4 is less than that of Ksp of BaCrO4 . so lesser Ksp value solid will be precipitate first
so answer : PbCrO4
