. The insoluble salts AV, B2W, C2X3, DY2, and EZ3, which were formed from the metal ions A+, B+, C3+, D2+, and E3+ and the nonmetal ions V1– , W2–, X2–, Y1–, and Z1–, all have the same Ksp value. The salt with the highest molar solubility is
AV
B2W
C2X3
DY2
EZ3
I think that C2X3 is the highest because it is C2^3+^ X3^2-^. The charges for the others are lower. Would you agree?
I agree that C2X3 has the highest solubility.
To determine which salt has the highest molar solubility among AV, B2W, C2X3, DY2, and EZ3, we need to consider the solubility product constant (Ksp) and the charges of the components.
The solubility product constant (Ksp) indicates the solubility of a salt in water. It is the equilibrium constant for the dissolution of the salt into its ions in a saturated solution. In this case, since all salts have the same Ksp value, we can conclude that their solubilities are equal.
However, the molar solubility of a salt also depends on the stoichiometry of the compound, specifically the charges of the metal and non-metal ions.
Let's consider the salts one by one:
- AV: This salt consists of the metal ion A+ and the non-metal ion V1-. Both ions have a lower charge compared to the other salts. The charges here do not indicate a high solubility.
- B2W: This salt consists of the metal ion B2+ and the non-metal ion W2-. Both ions have higher charges compared to AV, but the overall charge on the salt is balanced.
- C2X3: This salt consists of the metal ion C3+ and the non-metal ion X3-. The metal ion has the highest charge among all the salts, and both ions have higher charges compared to AV and B2W. Therefore, C2X3 is a strong candidate for having the highest molar solubility.
- DY2: This salt consists of the metal ion D2+ and the non-metal ion Y1-. The metal ion has a lower charge compared to C2X3, and the overall charge on the salt is balanced. Therefore, its solubility may be lower than C2X3.
- EZ3: This salt consists of the metal ion E3+ and the non-metal ion Z1-. The metal ion has a lower charge compared to C2X3, and the overall charge on the salt is balanced. Therefore, its solubility may also be lower than C2X3.
Based on the charges of the metal and non-metal ions, it is reasonable to conclude that C2X3 has the highest molar solubility among AV, B2W, C2X3, DY2, and EZ3.
