Introduction:
In this question, we need to determine which aqueous solution would contain the maximum concentration of S2- ions. To do this, we will compare the solubility product constants (Ksp) of the given sulfides and identify the one with the highest value.
Explanation:
The solubility product constant (Ksp) is an equilibrium constant that represents the extent to which a sparingly soluble compound dissociates into its ions in a solution. The higher the Ksp value, the more soluble the compound is in water, resulting in a higher concentration of ions.
We are given four sulfides: Mns, Zns, Pbs, and Cus. We will compare their Ksp values to determine which sulfide would yield the maximum concentration of S2- ions.
Comparison of Ksp values:
1) Mns (Ksp = 1.1×10^-21): This indicates that Mns is sparingly soluble in water, resulting in a low concentration of S2- ions.
2) Zns (Ksp = 1.1×10^-23): Zns is also sparingly soluble, but its Ksp value is lower than that of Mns. Therefore, the concentration of S2- ions in Zns solution would be lower than in Mns solution.
3) Pbs (Ksp = 1.1×10^-35): The Ksp value of Pbs is significantly lower than the previous two sulfides. This indicates that Pbs is less soluble in water, resulting in an even lower concentration of S2- ions.
4) Cus (Ksp = 1.1×10^-30): Among the given sulfides, Cus has the highest Ksp value. This suggests that Cus is the most soluble in water, leading to the highest concentration of S2- ions in its solution.
Conclusion:
Based on the comparison of Ksp values, the aqueous solution of Cus would contain the maximum concentration of S2- ions.
