Why the solution is boiled before titration?
Boiling the solution before titration helps to remove any dissolved gases that may interfere with the titration process. Additionally, heating the solution can help to dissolve the solute more effectively and improve the accuracy of the titration results.
Why must you rinse the titration flask with distilled water before further use?
Rinsing the titration flask with distilled water helps to remove any residue or impurities from the previous titration, which could affect the accuracy of the next titration. It ensures that the flask is clean and free of any substances that could interfere with the reaction being studied. This step is crucial for obtaining precise and reliable titration results.
Why do you need to remove the funnel before carrying out the titration?
Removing the funnel before titration ensures that all the liquid being added comes into direct contact with the solution being titrated. This helps to ensure accurate measurements and avoids any potential contamination from the funnel.
Why do you need to rinse your a buret before titration?
To wash out any trace chemicals. These trace chemicals coul affect the titration result. If the burette is clean ( from the lab. store), it will have been through the stores washing machine, so there may be trace solvents left behind.
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 oxygen error in association with iodometric titrations what can you do to overcome?
Oxygen error in iodometric titrations occurs when oxygen in the atmosphere reacts with iodide ions, interfering with the titration results. To overcome this, the sample can be titrated in an inert atmosphere or by adding a reducing agent to remove the dissolved oxygen. Another approach is to boil the sample to remove the dissolved oxygen before titration.
Why ist necessary to rinse the clean burette before filling it with the unstandardised sodium hydroxide solution?
It is important to rinse the clean burette to remove any residual contaminants or impurities that could affect the accuracy of the titration results. Additionally, rinsing helps to ensure that the burette is properly conditioned for the new solution being used. This step helps to avoid any potential errors or inaccuracies in the titration process.
Why you rinse titration flask with water?
Rinsing the titration flask with water is done to ensure that all of the titrant (the solution being titrated) is transferred into the flask for accurate measurements. By rinsing, you can be sure that no titrant is left behind on the walls of the flask, ensuring a complete reaction during the titration process.
Should I remove the child before washing the clothes?
Yes, it is important to remove the child before washing the clothes to ensure their safety and well-being.
Why is distilled water boiled before it used in preparing sodium hydroxide titrant?
Distilling water removes impurities and gases that could interfere with the accuracy of the titration. Boiling the distilled water helps to remove any residual volatile compounds that may be present, ensuring that the water used is as pure as possible for accurate titration results.
How a buret and pipette are cleaned for use in titration?
To clean a buret and pipette for use in titration, you should first rinse them with distilled water to remove any residue. Next, wash them with a suitable cleaning solution, such as a diluted acid or base depending on the titrant used. Finally, rinse them with distilled water again and allow them to dry before use.
Why is it important to wash rice before cooking and what does washing rice do?
It is important to wash rice before cooking to remove excess starch and debris. Washing rice helps to improve its texture, remove impurities, and prevent it from becoming too sticky when cooked.
