During titration why use a conical flask and not a beaker?
So you can swirl the contents around without spilling them. =]
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
What type of indicator is used during potassium permanganate titration?
Usually there is no indicator needed in potassium permanganate titrations as there will be an excess of manganate ions in the conical flask, turning the solution from colourless to pale pink.
What happens during an acidic base titration in the presents of an indication?
The indicator will change color as the pH changes.
What is the endpoint of a titration?
during a titration when a titrant completely furnished the sample then this is the end point of 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.

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.
What is the endpoint of a titration?
during a titration when a titrant completely furnished the sample then this is the end point of titration.
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 is the reason of heating solution during redox titration?
This is far to be a rule for this titration.
Why the titration flask need to be shake during titration?
so that the solutions mix properly
What is a potentiometric titration?
A potentiometric titration is one in which the end-point is detected by measuring the change in potential of a suitable electrode during the titration.
Difference between precipitation titration and complexometric titration?
During a precipitation titration an insoluble precipitate is formed.Complexometric titration is a type of volumetry which use as titrants EDTA or other similar reagents.
