What else can I help you with?
Why do you use conical flask in the titration process rather than beaker?
Conical flasks have a narrow neck that helps prevent splashing and allows for more controlled pouring of reagents. This makes them ideal for precise measurements and additions during titration. The conical shape also allows for easy swirling of the solution without spilling.
What is the procedure for determining the percentage purity of amino acid sample by sorenson formol titration method?
prepare about 1 to 1.5% solution of amino acid in 100 ml volumetric flask take 10 ml of the sample (amino acid) solution into 250 ml conical flask add phenophtalien indicator and titrate it against 0.1N standard NaOH when pink color appear stop the titration and add formalin untill the pink color disappear again titarte it with standard NaOH till the pink color reappear.
What happen if you adding water to the titrated substance in the conical flask during the process of titration?
NoUser 1Yes. By adding water to rinse, you will be changing the concentration of the thing you are titrating, and so your calculation will be off. If you have material on the walls of the flask, just gently stir the flask and let the solution in the flask wash anything off the walls.User 2I do not believe this is true. Once you add an amount of reactant into your flask adding more water will not change the number of moles of reactant that are present in the flask. The titrant will react in the mole ratio for that particular reaction so water doesn't play a role. You can rinse the flask and even use water to get part of a drop into your flask for a more accurate titration.User 3No. User 1 means to say that water in the volumetric burette or pipette will effect the concentration of titrant moles. Water in a conical flask will not effect the titre values because the same mole ratios are reacting, and your titre value is measured from the volume remaining in the volumetric burette and not the conical flask. User 2 is correct, although using water to rinse the volumetric burette's contents into the conical flask would adversely effect the results, as volumetric burettes and pipettes are designed to account for the few remaining drops in the instruments. Shaking or tapping the instruments is also a bad idea, as they can easily be broken and doing this would effect your titre values anyway.User 4It will not affect the result at all as long as you use distilled water, as just tap water obviously contains other minerals etc that will affect the results.
What is a conical flask used for?
An Erlenmeyer flask, commonly known as a conical flask or E-flask, is a widely used type oflaboratory flask which features a conical base and a cylindrical neck. They are usually marked on the side (graduated) to indicate the approximate volume of their contents. It is named after the German chemist Emil Erlenmeyer, who created it in 1861.
What are possible sources of error in a conductrimetric titration experimentWhy is the solution placed in the burette very much more concentrated than that in the conical flask Explain graphs?
Possible sources of error in a conductimetric titration experiment include temperature fluctuations affecting conductivity values, impurities in the solutions affecting conductivity readings, and improper calibration of the conductivity meter. The solution in the burette is typically more concentrated to ensure the endpoint can be easily detected during the titration. In the graphs obtained from the experiment, there is usually a sharp increase in conductivity at the equivalence point, indicating the completion of the reaction between the analyte and titrant.
Which solution in the titration is taken in conical flask?
The solution being titrated is placed in the conical flask. The titrant (the solution being added during titration) is then slowly added to the solution in the conical flask until the endpoint is reached.
Why does adding distilled water in the conical flask during titration not affect the titration result?
Adding distilled water in the conical flask during titration does not affect the titration result because the volume of the solution in the conical flask affects the concentration of the titrant solution. As long as the same volume of titrant is delivered from the burette and reacts with the analyte, the concentration of the titrant and the volume of the analyte solution will remain the same, ensuring accurate results.
Do you use titrant in conical flask?
yes we use titrant in the conical flask ,this is because titrant is a solution we use in burrete for titration in this process we titrant the solution in the conical flask along with an indicator
Why before doing titration conical flask is not rinsed?
The conical flask is not rinsed before performing titration because doing so could dilute the solution and alter the concentration, affecting the accuracy of the titration. It is important to maintain the concentration of the solution as accurately as possible for precise results.
Why does it not matter if conical flask you wet with water during titration?
Wetting the conical flask with water during titration helps to ensure thorough mixing and prevents solution splashing or clumping on the sides of the flask. This can help in obtaining accurate and consistent titration results.
Can a beaker be used instead of conical flask in titration?
Yes, a beaker can be used instead of a conical flask for titration. However, it is recommended to use a conical flask as it allows for easier swirling of the solution during the titration process, which can improve the accuracy of the results.
Why do you use conical flask in the titration process rather than beaker?
Conical flasks have a narrow neck that helps prevent splashing and allows for more controlled pouring of reagents. This makes them ideal for precise measurements and additions during titration. The conical shape also allows for easy swirling of the solution without spilling.
What is the name for a conical glass flask with a narrow neck and broad base?
Volumetric flask - used to prepare a standard solution in laboratory
Is there any difference between conical flask and titration lask?
Yes, there is a difference between a conical flask and a titration flask. A conical flask is a general-purpose laboratory glassware used for mixing and heating liquids, while a titration flask, also known as a burette, is a specific type of flask used in a titration to measure the volume of a substance being added to a solution. Titration flasks are usually marked with volume measurements to accurately determine the amount of substance added in a titration.
Why was the conical flask not washed with the alkali solution it was going to contain during titration?
So that no extra moles of NaOH were present in the flask.
What happens to a pH of a solutionin a conical flask during a titration?
During a titration, the pH of the solution in the conical flask typically changes as the titrant is added. The pH may increase, decrease, or remain constant depending on the nature of the reactants and products formed during the titration. The pH may reach a maximum or minimum at the equivalence point, depending on the type of titration being conducted.
What apparatus is used in titration?
A burette is typically used in titration to deliver a precise volume of a solution into another solution until the reaction reaches completion, as indicated by a color change or other observable change. The burette allows for the careful measurement of the volume of solution added during the titration process.
