The Ksp of Ag2CrO4, AgCl, AgBr and AgI are respectively, 1.1 x 10-12, ...
Explanation:
To determine which salt will precipitate last, we need to compare the solubility products (Ksp) of the four salts.
Solubility Product (Ksp):
Ksp is an equilibrium constant that measures the extent to which a slightly soluble salt dissolves in water. It is the product of the concentrations of the dissociated ions raised to the power of their stoichiometric coefficients. The higher the Ksp value, the more soluble the salt is.
Comparison of Ksp Values:
- Ag2CrO4: Ksp = 1.1 x 10^(-12)
- AgCl: Ksp = 1.8 x 10^(-10)
- AgBr: Ksp = 5.0 x 10^(-13)
- AgI: Ksp = 8.3 x 10^(-17)
Analysis:
We are adding AgNO3 solution to a solution containing equal moles of NaCl, NaBr, NaI, and Na2CrO4. When AgNO3 is added, Ag+ ions are formed, which can react with the anions of the salts to form insoluble silver salts.
In this case, the Ag+ ions will react with the anions Cl-, Br-, I-, and CrO4^2- to form AgCl, AgBr, AgI, and Ag2CrO4 respectively. We need to determine which of these salts has the lowest solubility product (Ksp) to find the one that will precipitate last.
Comparison:
- Ag2CrO4: Ksp = 1.1 x 10^(-12)
- AgCl: Ksp = 1.8 x 10^(-10)
- AgBr: Ksp = 5.0 x 10^(-13)
- AgI: Ksp = 8.3 x 10^(-17)
Conclusion:
From the comparison of Ksp values, we can see that Ag2CrO4 has the lowest Ksp value. Therefore, it has the lowest solubility and will precipitate last when AgNO3 is added to the solution containing equal moles of NaCl, NaBr, NaI, and Na2CrO4.
Answer:
Therefore, the correct answer is option A) Ag2CrO4.

Answer:
Therefore, the correct answer is option A) Ag2CrO4.
