A standard solution is a solution with a known concentration of a solute, used in various chemical analyses and experiments. These solutions are essential for accurate measurements in titrations and other quantitative analyses, ensuring that results are reliable and reproducible. To prepare a standard solution, a precise amount of solute is dissolved in a specific volume of solvent, often using distilled water. Common examples include solutions of sodium chloride or potassium permanganate, which are frequently used in laboratory settings for calibration and comparison purposes.
