Consider the following solubility data for various chromates at 25 °C.
The chromate that is the most soluble in water at 25 °C on a molar basis is:
BaCrO4
PbCrO4
Ag2CrO4
none of these
The salt with more Ksp is more soluble in water. Hence BaCrO4 is more soluble.
Draw a histogram to represent the following frequency distribution.
