The Ksp of cadmium oxalate is 1.5 x 10⁻⁸.
What is the Ksp of Cadmium Oxalate?
The solubility product constant (Ksp) is a measure of the solubility of a sparingly soluble ionic compound. For cadmium oxalate (CdC₂O₄), this value indicates the equilibrium between the undissolved solid and its ions in a saturated solution. A lower Ksp value generally means lower solubility in water.
Cadmium oxalate dissociates in water according to the following equilibrium:
CdC₂O₄(s) ⇌ Cd²⁺(aq) + C₂O₄²⁻(aq)
The Ksp expression for cadmium oxalate is:
Ksp = [Cd²⁺][C₂O₄²⁻]
Ksp Value for Cadmium Oxalate
The specific Ksp value for cadmium oxalate is a critical parameter for understanding its solubility behavior in various chemical contexts.
Compound | Chemical Formula | Ksp Value |
---|---|---|
Cadmium Oxalate | CdC₂O₄ | 1.5 x 10⁻⁸ |
Understanding Ksp
The solubility product constant (Ksp) helps chemists predict the extent to which an ionic compound will dissolve in water. It is particularly useful in:
- Predicting Precipitation: If the ion product (Qsp) exceeds the Ksp, precipitation will occur.
- Calculating Molar Solubility: Ksp can be used to determine the molar solubility of a compound, which is the concentration of the dissolved substance in a saturated solution.
- Common Ion Effect: Ksp is essential for understanding how the presence of a common ion affects the solubility of a sparingly soluble salt.
