Answer:
K. Yes, because Qsp > Ksp for iron(III) phosphate
Explanation:
Lithium chlorate is very soluble in water, that means has a big ksp.
Iron (III) phosphate has a ksp of 1.3x10⁻²²
Ksp formula of iron (III) phospate is:
FePO₄(s) ⇄ Fe³⁺(aq) + PO³⁻(aq)
Ksp = [Fe³⁺] [PO₄³⁻] = 1.3x10⁻²²
Molar concentration of Fe³⁺ and PO₄³⁻ is:
[Fe³⁺] = 0.340L ₓ (2.52x10⁻⁹mol / L) ÷ (0.354L + 0.520L) = 9.8x10⁻¹⁰M
[PO₄³⁻] = 0.520L ₓ (4.65x10⁻¹¹mol / L) ÷ (0.354L + 0.520L) = 2.78x10⁻¹¹M
Replacing in Ksp formula:
Qsp = [9.8x10⁻¹⁰] [2.78x10⁻¹¹M] = 2.72x10⁻²⁰
As Qsp > Kps, the equlibrium will shift to the right decreasing the ions concentrations producing FePO₄(s), a precipitate
The ions decreases its concentration until Q = Kps
Thus, right answer is:
K. Yes, because Qsp > Ksp for iron(III) phosphate
