Why heating is done during the titration in fehling's test of reducing sugars?
Heating is done during the titration in Fehling's test to accelerate the redox reaction between the reducing sugar and the Fehling's reagent. This helps in speeding up the formation of the red precipitate, which consists of cuprous oxide, making it easier to detect and measure the reducing sugar concentration effectively.
What is a titrand in titration analysis?
A titrand is the substance in a chemical reaction that is analyzed or measured during a titration. It is the substance that undergoes a change in its chemical properties due to the addition of a titrant during the titration process.
What is pilot titration?
Pilot titration is a preliminary test to determine the approximate endpoint of a titration process before conducting the actual titration. It helps in estimating the volume of titrant needed for the main titration, ensuring more accurate and efficient results. The data obtained from a pilot titration can help in planning and executing the main titration with greater precision.
Why the titration flask need to be shake during titration?
Shaking the titration flask during titration helps to ensure that the reaction mixture is well-mixed and that the titrant is evenly distributed throughout the solution. This promotes a more uniform reaction and more accurate measurement of the endpoint of the titration.
Why need to add reagent drop by drop during titration?
Adding reagent drop by drop during titration allows for precise control of the reaction and helps prevent over-titration. This ensures that the endpoint is accurately determined and the titration results are as precise and reliable as possible.
