.. the substance is soluble
A soluble substance is a substance that can dissolve in another substance.
Solvent
A substance which can dissolve in a solvent is said to be soluble in that solvent
Something that can dissolve. A substance that is water-soluble can be dissolved in water.
There is no such thing as a soluble precipitate A precipitate a solid that is formed in a chemical reaction, therefor only a insoluble precipitate can occur, and the soluble would remain as a soluble solution. The difference between a soluble and insoluble precipitate is that a insoluble precipitate is incapable of dissolving in a liquid, and a solid is formed in the reaction, where as the soluble substance will dissolve in the liquid.
The prefix for "soluble" is "sol-," which comes from the Latin word "solvĕre," meaning "to loosen" or "to dissolve." In this context, "soluble" describes a substance's ability to dissolve in a solvent, typically water. Other related terms include "insoluble," which indicates a substance that does not dissolve.
Insoluble.
The substance is hydrophobic, meaning it repels water and does not dissolve in it.
The substance is said to be soluble or dispersible.
Least soluble means that a substance has a low ability to dissolve in a particular solvent. This may result in insolubility or the formation of a suspension where the substance does not fully dissolve and remains suspended in the solvent.
Sparingly soluble means a substance dissolves only in small amounts in a solvent. This relates to the solubility of a substance by indicating that it does not fully dissolve in a solvent, leading to a limited amount of the substance being able to dissolve in the solvent.
