Titration Techniques and Procedures

This video tutorial provides a detailed guide on performing a titration experiment. It covers the preparation of equipment, including cleaning and filling the pipette and buret, and the step-by-step process of conducting the titration. The video emphasizes accuracy in measurements and the importance of repeating trials to ensure reliable results. It concludes with instructions on cleaning up and storing equipment properly.

What is the first step in preparing for a titration experiment?

• Filling the buret with alkali

• Gathering all necessary equipment

• Wearing gloves and goggles

• Adding the indicator to the solution

How should the pipette be cleaned before use?

• By rinsing with tap water

• By filling it completely with acid

• By soaking in a cleaning solution

• By washing with distilled water

What is the purpose of filling the pipette with acid?

• To transfer a specific volume of acid to the conical flask

• To measure the alkali

• To calibrate the pipette

• To clean the conical flask

Why is it important to remove air bubbles from the buret?

• To avoid chemical reactions

• To speed up the titration process

• To ensure accurate volume measurements

• To prevent contamination

What should be placed under the flask during titration to help observe the color change?

• A black tile

• A white tile

• A glass plate

• A metal sheet

What is the main goal of the first titration trial?

• To achieve perfect accuracy

• To get a rough estimate of the endpoint

• To clean the equipment

• To use up all the acid

How should the liquid be released from the buret during the second trial?

• Drop by drop for accuracy

• Without any specific method

• Quickly and continuously

• In large amounts

What should be done if the buret is not empty after the first trial?

• Refill it to the 0 ml mark

• Leave it as it is

• Add more acid

• Empty it completely

How many titration readings should be taken to ensure accuracy?

• At least two

• At least four

• At least one

• At least three

What is the final step after completing the titration trials?

• Recording the results in a new worksheet

• Dismantling the setup and cleaning the equipment

• Adding more alkali to the buret

• Rechecking the initial volume
