Why do you use conical flask in the titration process rather than beaker?
It prevent the solution from spelling
What instrument is used in measuring?
Titration involves the use of a buret and also an Erlenmeyer flask or beaker (where it is measured).
Why is that when NaOH H2SO4 and phenophtalein in conical flask becomes hot after shaking during titration?
The reaction between NaOH and H2SO4 is highly exothermic, meaning it releases heat. When the solutions are mixed in the conical flask and shaken during titration, this reaction occurs and produces a significant amount of heat. Additionally, the presence of phenolphthalein might contribute to the sensation of heat as it can change color when exposed to heat or pH changes, indicating the progress of the reaction.
Could a 25 ml volumetric flask be replaced by a 25 ml pipette to measure the solution poured into a conical flask for titration?
As the pipette is far more accurate than a flask by a factor 10 to 100 one should NOT use a volumetric flask except for standard volumes over 100 ml.
What will happen to the molarity of NaOH If a drop of NaOH falls out of the flask during the titration?
You have to realise that a drop from the burette for instance is insignificant, if you are dealing with at least 10ml solution which you usually deal with on a titration. If you don't want to regard it as insignificant, then if NaOH is in the burette, then the solution doesn't become more concentrated with NaOH because that drop escaped.
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.
Why the titration flask need to be shake during titration?
so that the solutions mix properly
Why you rinse titration flask with water?
To remove any substance that is already present in the titration flask from the previous titration
During titration why use a conical flask and not a beaker?
So you can swirl the contents around without spilling them. =]
What is the titration flask?
It is the conical flask in which the solution from the burette flows into and which you add the indicator into.
Can a beaker be used in a titration instead of an erlenmeyer flask?
Yes.
What apparatus is used in titration?
A burette, a pipette and conical flask
What measuring instrument is used in titration?
Titration involves the use of a buret and also an Erlenmeyer flask or beaker (where it is measured).
Why is sulfuric acid added to the dilute bleach and iodide in the conical flask during titration of sodium hypochlorite with sodium thiosulphate?
to acidify the solution
When performing titrations why should you constantly stir the contents?
During a titration, reactant from the burette are added drop wise. It may not reach the bottom, which might result in an incorrect endpoint. The flask is always stirred to mix the reactants in the flask evenly.
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 is it necessary to rinse the conical flask with distilled water for titration?
It is necessary due to the conical flask may not be clean. deionised water is necessary as opposed to water due to the fact that alot of titrations if not all involve ions. if extra ions are added from the water the equivilance point could be off by a few tenths of a ml. Rinsing in general is necessary due to the fact that you never know what was held in the flask beforehand, and in nearly all cases it would upset your results. although, if you have no deionised water, it would upset your results less if you cleaned glasswear with normal water than if you used dirty glasswear. I recently won a competition that was part titrimetric, so I'm confident in my technique as thought by my lab technician. quick wash with tap water twice, then quick rinse with deionised twice. if anything impure remains, it will be so dilute that it shouldn't affect results.
