Question

How many grams of cac2o4 will dissolve in distilled water to make one liter saturated solution?

Answer 1

Given data:

Solubility product constant (Ksp) of CaC2O4 is approximately equal to 2.5 * 10^-9 M^2 (i.e) 25 * 10^-10 M^2

Molecular weight is 128

Formula:

We know that Ksp = S^2

S = Squareroot(Ksp)

S = Squareroot(25 * 10^-10 M^2)

S = 5 * 10^-5 * M

S = 5 * 10^-5 * 128

S = 0.0064

0.0064g of CaC2O4 will dissolve in distilled water to make one liter saturated solution.

Hope it helps. Thank You!
