AP Chemistry· difficulty 4/5

Selective precipitation works because

A
$K_sp = 0 for some salts$
B
$All salts have the same K_sp$
C
$Different K_sp values reach Q = K_sp at different ion concentrations$

D
$Solubility depends only on T$

Explanation

By controlling added precipitant, the less soluble salt precipitates first.
