A solution can be both____________________?
Correct answer: A. dilute and concentrated
- A. dilute and concentrated
- B. dilute and saturated
- C. saturated and unsaturated
- D. saturated and super saturated
Explanation
A solution may be both dilute and saturated when the solute has low solubility: it contains only a small amount of solute, yet that amount is the maximum possible at that temperature. A student may choose c, confusing saturation with concentration and assuming that a saturated solution cannot be dilute.

About Solubility Product
The solubility product constant, Ksp, represents the equilibrium concentrations of ions from a sparingly soluble salt, each raised to its stoichiometric power. Problems involve writing Ksp expressions, calculating molar solubility, applying the common-ion effect and predicting precipitation from the ionic product.
