A dilute solution is a mixture where a small amount of solute is dissolved in a larger amount of solvent. For example, when you add a teaspoon of sugar to a glass of water, the sugar is the solute, and the water is the solvent. The resulting mixture has a low concentration of sugar, making it a dilute solution. Dilute solutions are commonly used in various fields, including chemistry and biology. They are important for experiments and processes where precise concentrations are needed, such as in the preparation of chemical reactions or in medical treatments where specific dosages are crucial.
