the quantity of a particular substance that can dissolve in a particular solvent (yielding a saturated solution)
"The lab report notes that the solubility of sugar in cold water is significantly lower than in hot water."
the property (of a problem or difficulty) that makes it possible to solve
"After weeks of staring at the code, I finally realized my frustration came from the low solubility of the bug rather than its complexity."
the quality of being soluble and easily dissolved in liquid
"The chemist adjusted the temperature to increase the solubility of the sugar so it would dissolve completely in the hot water."
The condition of being soluble.
"The solubility of sugar in hot water is significantly higher than it is in cold water."
