Need of blank titration?
to reduce error
What is a titration and what equipment would you need?
A titration is a process of nutrilising an acid. You would need a burette, a beaker and and acidic and alkali substance. Higher chem FTW
Why there is a need to warm the solution of sulfuric acid and oxalic acid during redox titration?
Adding heat to a reaction usually speeds up a reaction.
Why do you need to Swirl during titration?
It just helps to mix the two solutions better adn quicker. If you don't swirl your results are going to be a little off.
Why do you need to remove the funnel before carrying out the titration?

How get the accutare titration value?
Titration value describes how accurately a substance is dissolved in another substance. In order to find this number, you need a pipette, a burette, and a volumetric flask.

What is the need for an ammonical buffer solution in the determination of hardness of water by edta titration?
during the complexometric titration using edta it is very necessary to maintain the ph of the solution near about 10 so we use ammonium chloride buffer if we will not use this buffer dring the titration ph of sol. will ho lower side

How do clean a beaker?
Acid washing it should do. I assume you are in a lab...in which case a 1:1 Hydrochloric Acid solution can be poured into the flask. DON'T FORGET TO PUT GOGGLES AND GLOVES ON. Put the lid on. Shake the flask and turn it to ensure all surfaces of the glass inside are being washed with the acid. Then, give it a good triple rinse with de-ionized water. If you are just at home, pour in some white vinegar and let it sit for a while. That should break up anything that's inside.
How did James dewar invent the vacuum flask?
During an experiment, James Dewar formed a brass chamber that he enclosed in another chamber to keep the palladium at its desired temperature. He evacuated the air between the two chambers, and through the need for this insulated container, he created the vacuum flask.
How does concentration affect a titration?
It is easier to answer this by using examples. Let us suppose we have 4g of NaOH in 100 mls of waste water (4%). Titrating with 1M HCl would require 100ml of titrant. That would thus mean we would need 1000ml of 0.1M HCl titrant run from a buret which is extremely impractical. The concentrations thus affect volumes and thus titration flask sizes etc. It also would affect the time taken and the practicality.
What is radiometric titration?
Radiometric titration is "regular" titration, but with the incorporation of a radioactive indicator to monitor the end-point. And that's right from the IUPAC Compendium of Chemical Terminology. If you need an example, use the link provided to a post on the radiometric titration of hexachloro-platinate (IV). It's a bit esoteric, but it will serve to exemplify the idea behind radiometric titration. It's pretty clear that when working with two precipitates (co-precipitation), the analyst would need a way to differentiate them. In the case cited, the application of radioactive cæsium-137 will permit the observer to more quickly and easily find a cutoff point at which to terminate the titration.
Why Erlenmeyer flask does not have to be dry and why water may be added?
- Depending on the specifications for the experiment the Erlenmeyer flask may be dry or not - Water is added only if the recipe need water
