Preparation of standard solutions involves accurately dissolving a known quantity of a pure substance (the solute) in a specific volume of solvent to achieve a solution with a precise and known concentration. This process typically includes:
Weighing the Solute: Accurately measuring the exact amount of solute using an analytical balance.
Dissolving the Solute: Adding the solute to a volumetric flask and dissolving it in a portion of the solvent.
Dilution to Volume: Adding more solvent to the volumetric flask until the solution reaches the desired final volume.
Mixing: Thoroughly mixing the solution to ensure uniform concentration throughout.
Standard solutions are essential for various analytical techniques, such as titration, calibration of instruments, and quality control in laboratories.
