How to Calc molar concentration from Ksp

[bman9620]

What is the Molar Concentration of Sr(CO3)3 if Ksp=9.3 X10^-10

I believe you have to balance the equation and i got
Sr(CO3)3= Sr + 3 CO3

Yes... and you have to write out the expression for Ksp as well. And you have to plug in a variable into that expression.

To calculate the molar concentration from Ksp, we need to use the equation for Ksp, which is the product of the concentrations of the ions in a saturated solution of the compound. In this case, the equation would be Ksp = [Sr][CO3]^3. We can rearrange this equation to solve for the molar concentration of Sr(CO3)3, which would be [Sr(CO3)3] = (Ksp/[CO3]^3)^1/3.

Substituting the given Ksp value of 9.3 x 10^-10 and assuming a concentration of [CO3] = 1 M (since Sr(CO3)3 has a 1:3 ratio with CO3), we can calculate the molar concentration of Sr(CO3)3 to be 3.6 x 10^-4 M.

It is important to note that this calculation assumes ideal conditions, and the actual molar concentration may vary depending on factors such as temperature and other ions present in the solution.
