Solubility of KCIO3 gives__________________?
Correct answer: C. continuous and rising solubility curve
- A. continuous and falling solubility curve
- B. discontinuous and falling solubility curve
- C. continuous and rising solubility curve
- D. discontinuous and rising solubility curve
Explanation
The solubility of KClO3 increases continuously as temperature rises because no solid-state transition interrupts the curve, and the solubility generally increases with temperature. Students may choose K2Cr2O7 because it also has a rising curve, but the question asks for the stated behaviour of KClO3.

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.
