The outside of the burette is wiped with a paper towel before titration to ensure that any liquid droplets on the outer surface do not affect the accuracy of the titration by inadvertently entering the solution being titrated. This helps to prevent contamination and ensure precise measurements are obtained during the titration process.
What else can I help you with?
End point of titration should be at pH?
A titration usually has an acid (pH 0-6) in the burette and an alkali (pH 8-14) in the conical flask below the burette. Your aim is to neutralise the two solutions by titrating them against each other.So the endpoint pH should be 7 (universal indicator/litmus paper will appear a greenish colour). The solution in the conical flask is neutral.Hope this Helps!
Why was the conical flask placed on a white piece of paper in titration?
The white paper helps to provide a clear background for observing color changes during the titration process. This is important for accurately determining the endpoint of the titration when the color changes indicate the completion of the reaction.
Why do you put a white paper under the titration flask?
A white background makes it easier to see color changes in the solution during titration, improving the accuracy of the endpoint determination. It enhances the visibility of subtle color changes, ensuring the titration results are more precise and reliable.
How can you tell if the burrette contains the acid or base?
You can determine if a burette contains acid or base by using a pH indicator. Simply add a few drops of the indicator to the solution in the burette and observe the color change. Red or pink indicates an acid, while blue or green indicates a base.
Why do you use external indicator in diazotization titration?
external indicator is required in diazotization as to observe the end point of the reaction. internal indicators cannot give the endpoint because they may form complexes which may cause hindrance. for example, in the assay of sulfa drugs, iodine-starch paste is used as external indicator, because if we add iodine paste in the conical flask it will react with the reactants and give the blue-black coloration in the beginning of the actions, which will not tell the end point of the reaction. instead, the iodine-starch paste is applied in a paper, and the compound from the burette is added in small quantities into the sulfa drug solution, and after every few milliliters a drop of solution from the conical flask is dropped on the iodine-starch paste, when there is sudden change in colour, the addition from the burette is stopped. and observations are made.

No, you do not have to grease parchment paper before using it.
Can you attach magnets to the outside of a microwave oven to hold paper?
It is not recommended to attach magnets to the outside of a microwave oven as they can interfere with the oven's operation. Instead, consider using adhesive hooks or clips to hold paper on the outside of the microwave.
