6-2.Equilibrium-II (Ionic Equilibrium)
medium
Which of the following does not give ppt with $CrO _{4}^{-2}$
A
$Ca^{2+}$
B
$Sr^{+2}$
C
$Pb^{+2}$
D
$Ba^{+2}$
(AIIMS-2019)
Solution
The cation $Ca ^{+2},$ which is from $V^{th}$ group, is not able to give ppt with $CrO _{4}^{-2}$ as its has high solubility.
Order of $Ksp \Rightarrow BaCrO _{4} < SrCrO _{4} < CaCrO _{4}$
