Water soluble compounds are substances that can dissolve in water, forming a homogeneous solution. This property is often due to the presence of polar bonds or ionic structures, which interact favorably with water molecules. Common examples include sodium chloride and sugar, which readily dissolve when mixed with water. When a water soluble compound dissolves, its molecules or ions separate and disperse throughout the water. This process is essential in various biological and chemical processes, such as nutrient transport in plants and the functioning of cells. Understanding water solubility is crucial in fields like chemistry and pharmacology.
