Answer 1

Volumetric flask

Step-by-step 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.
