AgCl (aq)
Option: 4
Explanation:
AgCl has the lowest concentration of dissolved ions because it is insoluble. Hence, it does not allow any ions into the solution.
According to the Solubility rule, the salts that have Cl⁻ are usually soluble but Ag⁺ is an exception which shows that AgCl is insoluble. It is insoluble because the lattice structure of AgCl is very strong that it cannot be overcome by the forces that favor the formation of hydrated ions, Ag⁺(aq) and Cl⁻(aq). Solubility of AgCl in water is very low but however, it can precipitate in water.
The saturated solution that contains the concentration of dissolved ions is AgCl (aq)
AgCl should contain a less concentration of dissolved ions due to insoluble. Due to this, it permits any ions into the solution. As per the above rule, the salts that have Cl⁻ are normally soluble however Ag⁺ should be an exception which represents that AgCl is insoluble. It is insoluble due to the lattice structure of AgCl should be very strong. The solubility of AgCl in water should be very low but it should be precipitated in water.
Hence, The saturated solution that contains the concentration of dissolved ions is AgCl (aq)
