Insoluble materials are substances that do not dissolve in liquids like water. When added to water, these materials do not mix or form a solution; instead, they remain separate and can often be seen as solid particles. For example, sand, oil, and wood are insoluble in water. These materials either float on top or sink, but they do not dissolve into the liquid. Understanding which materials are soluble or insoluble helps in different tasks, such as separating mixtures or understanding how substances interact with water.
