Titration Flashcards
What is the first step in the titration process?
Rinse the burette with distilled water and then rinse two or three times with a known concentration of sodium carbonate.
How should the pipette be prepared before use?
Rinse the pipette with distilled water and then rinse two or three times with dilute hydrochloric acid.
What is the purpose of rinsing the conical flask?
Rinse the conical flask with distilled water.
How do you transfer the sodium carbonate solution to the burette?
Use a funnel to transfer the sodium carbonate solution to the burette.
What is the method for obtaining a fixed volume of dilute hydrochloric acid?
Use a pipette filler to obtain a fixed volume of dilute hydrochloric acid and add to a conical flask.
What indicator is added to the conical flask during titration?
Add a few drops of phenolphthalein indicator to the conical flask and swirl.
Where should the conical flask be placed during the titration?
Place the conical flask on a white tile.
What should be done during the rough titration?
Carry out a rough titration and keep swirling until the endpoint is reached.
How should the accurate titration be performed?
Repeat the experiment to obtain an accurate titration. Add the solution dropwise near the endpoint and keep swirling.
How many concordant results should be obtained?
Repeat the experiment until 3 concordant results are obtained.
