The K sp of AgCl and Ag 2 CrO 4 are 1.8 × 10 -10 and 2.0 × 10 -12 , respectively. Which is the correct statement?
A.
Solubilities of these two compounds are same.
B.
The solubility of AgCl is larger than Ag 2 CrO 4.
C.
We cannot compare their solubility directly from their K sp values because they are different types of precipitates.
D.
They both are insoluable so the solubility is meaningless.
