Aqueous solutions are mixtures where water is the solvent, meaning it dissolves other substances, called solutes. Common examples include saltwater, where sodium chloride dissolves in water, and sugar water, where sucrose dissolves. The properties of the solution depend on the solute and its concentration. In an aqueous solution, the solute particles are evenly distributed throughout the water, allowing for various chemical reactions. These solutions are essential in many fields, including chemistry, biology, and environmental science, as they facilitate processes like dissolution, reaction kinetics, and transport of nutrients.
