Which of the following is the best piece of laboratory glassware for preparing 500.0 ml of an aqueous solution of a solid? (a) volumetric flask(b) erlenmeyer flask(c) test tube(d) graduated beaker(e) graduated cylinder

Option A. Volumetric flask

Explanation: volumetric flask is used in preparing standard solutions to specific or definite.

Note: Graduated beaker can only be used to estimate roughly the volume of a liquid.

Volumetric flask

Explanation:

When preparing a standard solution, a volumetric flask is the best piece of equipment required. The volumetric flask is a special equipment designed with a mark. The mark shows the required volume of solution.

The solute is added to the flask and simply made up to mark with distilled water to prepare a solution of the required volume in a particular volumetric flask of that volume.
