Question

Determination of Ksp value given concentration of Ca2+ is 7.72705 ppm, and pH =9.24, and chemical equations (some sort of derivation using these equations and above values is needed to calculate the Ksp value)

Determination of Ksp of CaCO3 based on the measured pH and the following equations:
CaCO3 (s) Ca 2+ + CO3²-
[Ca ²+ ][CO,¹] = K
(1)
CO3+H₂O HCO3 + OH
[HCO, ][OH] K
(2)
[CO,2]
K₂
HCO3 + H₂O + H₂CO3 + OH
[H₂CO,][OH] K
[HCO,"]
=
K,
2H₂O → H3O+ + OH*
[H,O'][OH] = K
(3)
