What is the molar solubility of CaF2 in a saturated solution? (Ksp for CaF2 = 3.4 10-11.)?

Answer 1

Ksp is just te euqilibrium constant for the reaction

CaF2(s) <==> Ca2+ (aq) + 2 F- (aq)

Let solubility be x. Then [Ca2+] = x, [F-] = 2x (2 F- per formula unit)

Ksp = [Ca2+][F-]^2 (definition) = x(2x)^2 = 4x^3

Shove in the value for Ksp, and solve.

Click the "more problems" link near the bottom and one of the examples is CaF2, albeit with a different value for the Ksp

Answer 3

you're taking those 2 verses out of context. What are the matters of the two verses? Matthew 10:34-- concern: "Mat 10:35 For i'm come to set a guy at variance against his father, and the daughter against her mom, and the daughter in regulation against her mom in regulation. " Jesus Christ got here to disagree with that it somewhat is often happening that's no longer of God between a son and a father, and so on... --- "Psa 29:eleven The LORD will provide power unto his human beings; the LORD will bless his those with peace." The Lord does provide power and peace to those that love God. extraordinarily people who confess Christ to others. extraordinarily people who reason variance between people who stick to the international quite of God.
