Insoluble

The term “insoluble” refers to a substance that does not dissolve in a particular solvent. This could be due to a variety of factors, including the size and shape of the particles, as well as the chemical properties of the solvent and solute. When a substance is described as insoluble, it means that it cannot be dissolved in a given solvent, no matter how much of the solvent is used. This property is often important in fields such as chemistry, pharmaceuticals, and materials science, where the solubility of a substance can have a significant impact on its properties and behavior. Despite being insoluble in a particular solvent, a substance may still have other valuable properties, such as being a good electrical conductor, having a high melting point, or possessing antimicrobial activity.
