At 60°C, potassium chlorate, or KClO₃, is a non-polar material that dissolves least readily in water.
The capacity of a material, called a solute, to combine with a solvent or another molecule, is known as solubility in chemistry.
The primary characteristic is that similar-polarity compounds have a tendency to dissolve in one another ("like dissolves like").
The solubility product constant of a salt is the measure of how much of the salt dissolves in water. The current temperature is 60°C.
Because the saturated solution is heated, potassium nitrate (KNO3) is more soluble than potassium chlorate (KClO₃). It is soluble in 110 grams of NaNO3 for every 100 grams of water at 60 degrees Celsius.
