Question

which of these saturated solutions has the lowest concentration of dissolved ions?

A)NaCl [aq]
B)MgCl2 [aq]
C)NiCl2 [aq]
D)AgCl2 [aq]

Answer 1

Answer:

D) AgCl

Step-by-step explanation:

The soubility rules state that salts containing Cl⁻ are generally soluble. An important exception is Ag⁺.

Thus, AgCl is insoluble and it has the lowest concentration of dissolved ions.

A), B), and C) are wrong, because all the compounds are soluble.

Answer 2

A saturated solution of AgCl has the lowest concentration of dissolved ions.

A saturated solution is a solution that contains just as much solute as it can normally hold at a particular temperature. The solubility of a substance is defined as the amount of that substance that can dissolve in one litre of solvent.

Looking at all the options, we can see that AgCl has the lowest solubility because the salt is insoluble in water hence, a saturated solution of AgCl has the lowest concentration of dissolved ions.
