69. Calculate the Ksp for each of the salts whose solubility is listed below.
a) CaSO4 = 3.3 x 10-3 mol/L
b) MgF2 = 2.7 x 10-3 mol/L
Answers:
a) Solution
1. Write the dissociation reaction and the Ksp expression for the equilibrium reaction. Thus,
CaSO4(s) <---> Ca2+ (aq) + SO42-...
The solubility of M2X3 (as M3+ and X2-) in water at 298K is 4.12 x 10-4 M. Calculate Ksp for M2X3.
M2X3 <--> 2M3+ + 3X2-
K_sp = [M3+]^2*[X2-]^3
Now Molarity of M3+ = (4.12 x 10-4) M2X3*(2 mol M3+/1 mol M2X3) = 8.24E-4 mol = Molarity
Molarity X2- = (4.12 x 10-4) M2X3*(3 mol X2-/1 mol...
I am having a tough time with getting my heard around what Ksp is; this question isbugging the heck out of me:

Hi, We did a lab the other day involving the calculation of Ksp values.
Objective of the lab was to calc the Ksp of CaSO4 by several methods and to determine which method would give the most consistent/accurate value for the solubility product constant.
Heres what we did:
A) 1. Filter...
Maybe I am doing something horribly wrong here, but these numbers just make absolutely no sense to me.
We are given solubility values which will subsequently be used for Ksp calculations.
I was given hydrogen bromide and 5 solubility values (given in g/100g H2O)
Since 1g = 1mL basically...
