How to Use a Volumetric Flask for Solution Preparation?
To use a volumetric flask, follow these steps:
Clean the flask thoroughly to avoid contamination. Add the solute to the flask. Fill the flask about halfway with solvent and swirl to dissolve the solute. Carefully add more solvent until the bottom of the meniscus is at the graduation mark. Cap the flask and invert it several times to ensure homogeneity.
