Two sparingly soluble chlorides are considered at 25 °C.
• Salt C: Ksp=4.0×10−12
• Salt D: Ksp=1.0×10−8
Each salt is separately equilibrated with 0.010 M NaCl. Which salt undergoes the greater percent decrease in molar solubility relative to its solubility in pure water?
a) Salt D
b) Both salts undergo the same percent decrease.
c) Salt C
d) There is insufficient information to decide.
