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.

Why is the solution of sodium oxalate heated to 80 - 90 degrees C before titration?
Heating the solution of sodium oxalate helps to increase the reaction rate during titration. It helps to ensure that the titration proceeds quickly and efficiently. Additionally, heating can help to evaporate any excess water in the solution, leading to more accurate results.
Why thiosulphate titration is called as redox titration?
A thiosulfate titration is mostly carried out to determine the amount of iodine present in the solution. In these reactions, thiosulfate ion acts as the reducing agent. This types titrations are often called as 'iodometric titrations'.
Why must have gross reading in titration process?
to get rough volume....
Why oxalic acid is heated before titration with KMnO4?
Heating oxalic acid before titration with KMnO4 helps to remove any water of crystallization, making the compound anhydrous. This ensures accurate measurement of the substance being titrated and helps to prevent interference from water during the titration process. Additionally, heating can help to dissolve the oxalic acid more effectively, ensuring a more efficient reaction during titration.
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 the reason of heating solution during redox titration?
This is far to be a rule for this titration.
What is the chemistry behind the redox titration?
Redox titration involves a reaction between an oxidizing agent and a reducing agent. During the titration, electrons are transferred from the reducing agent to the oxidizing agent, resulting in a change in oxidation states. The equivalence point is reached when the moles of the oxidizing agent are stoichiometrically equivalent to the moles of the reducing agent.

How does DCPIP titration determine vitamin C concentration?
DCPIP titration is a method used to determine vitamin C concentration by measuring the amount of DCPIP reduced by vitamin C. Vitamin C is a reducing agent and will reduce the blue dye DCPIP to a colorless compound. The concentration of vitamin C can be calculated based on the volume of DCPIP solution consumed during the titration.
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.
After hydrolysis did sucrose give a positive test with fehlings test why orwhy not?
Sucrose would not give a positive test with Fehling's reagent after hydrolysis because sucrose is a non-reducing sugar. During hydrolysis, sucrose is broken down into its monosaccharide components (glucose and fructose), which are reducing sugars and can react with Fehling's reagent to give a positive test for reducing sugars.
What is a titration-quenching?
Titration quenching is a process where a substance is added to a solution to stop a chemical reaction or change in pH during a titration experiment. This substance helps to stabilize the solution at the endpoint of the titration, ensuring accurate results.
