10 Questions
Explain the aim of the procedure for Volumetric Flask Calibration.
The aim is to calibrate a volumetric flask for accurate volume measurements in laboratory experiments.
List five materials required for Volumetric Flask Calibration.
- Volumetric flask 2. Distilled water 3. Weighing balance 4. Weighing container 5. Graduated cylinder
What is the first step in the procedure for Volumetric Flask Calibration?
Clean the Volumetric Flask: Ensure the volumetric flask is clean and free from any residues. Rinse it with distilled water.
How should the volume be measured when filling the Volumetric Flask?
Be precise in measuring the volume using a pipette.
What should be done after filling the Volumetric Flask with water?
Weigh the volumetric flask containing the water and record the mass.
What is the aim of the preparation of distilled water?
To produce distilled water for laboratory use through the process of distillation.
What is the principle behind the process of distillation?
Distillation is a separation process based on differences in boiling points. By heating water, allowing it to vaporize, and then condensing the vapor, impurities are left behind, resulting in pure distilled water.
List three materials required for the preparation of distilled water.
- Distillation apparatus (flask, condenser, collection container) 2. Tap water 3. Bunsen burner or heating source
What is the theory behind the distillation process?
Distillation involves the conversion of water into vapor through heating and subsequent condensation of the vapor to produce distilled water. The process separates contaminants and impurities from the water, ensuring a high level of purity.
What is the first step in the procedure for the preparation of distilled water?
Assemble the distillation apparatus with a tight connection between the flask and condenser.
