Question

In Which solution will AgCl be most soluble?

A) 1.0 M AgNO₃

B) 0.01 M NaCl

C) 0.1 M MgCl

D) 2.0 M KNO₃

Answer 1

D) 2.0 M

AgCl precipitate will show following equilibrium in aqueous solution

A) 1.0 M , B) 0.01 M NaCl and C) 0.1 M provides common ion ( either silver ion or chloride ion). Hence, the equilibrium will shift to left and AgCl will be least soluble.

D) 2.0 M does not provide any common ion. Hence, AgCl will be most soluble.
