Answer to Problem 22.62QP

Solution

The Ksp value of Ca10(PO4)6F2 is 10.24×10120_ .

Explanation of Solution

Explanation

Given

The Ksp value of Ca5(PO4)3F is 3.2×1060 .

The dissolution of Ca5(PO4)3F in water is,

Ca5(PO4)3F5Ca2++3(PO4)3+F

The Ksp for Ca5(PO4)3F is calculated by the formula,

Ksp=[Ca2+]5[(PO4)3]3[F]1

Substitute the given value of Ksp for Ca5(PO4)3F in water in the above expression.

3.2×1060=[Ca2+]5[(PO4)3]3[F]1 (1)

The dissolution of Ca10(PO4)6F2 in water is,

Ca10(PO4)6F210Ca2++6(PO4)3+2F

The Ksp for Ca10(PO4)6F2 is calculated by the formula,

KspofCa10(PO4)6F2=[Ca2+]10[(PO4)3]6[F]2={[Ca2+]5[(PO4)3]3[F]1}2

Substitute the value of equation (1) in above expression.

Ksp=(3.2×1060)2=10.24×10120_

Therefore, Ksp value of Ca10(PO4)6F2 is 10.24×10120_ .

Conclusion

The Ksp value of Ca10(PO4)6F2 is 10.24×10120_ .
