Erlenmeyer Flasks are graduated, meaning they have calibrated lines to help detect the level the solution reaches, much like a graduated cylinder does. Knowing the relative level is important during titrations because they are usually done over many many times and its good to know when the change will take place approximately. But then again burrettes also have calibrated line which are much more accurate.
Basically I think it boils down to the idea that a flat bottomed flask is less likely to tip over than a round bottomed, volumetric one.
So why not just use a beaker? Well probably to avoid from any solution bouncing out as the drops fall into the solvent. A beaker just has a much larger opening at the top.
Regardless though, its convention in the chemistry community.
What else can I help you with?
Why was the conical flask placed on a white piece of paper in titration?
The white paper helps to provide a clear background for observing color changes during the titration process. This is important for accurately determining the endpoint of the titration when the color changes indicate the completion of the reaction.
End point of titration should be at pH?
A titration usually has an acid (pH 0-6) in the burette and an alkali (pH 8-14) in the conical flask below the burette. Your aim is to neutralise the two solutions by titrating them against each other.So the endpoint pH should be 7 (universal indicator/litmus paper will appear a greenish colour). The solution in the conical flask is neutral.Hope this Helps!
Why do you put a white paper under the titration flask?
A white background makes it easier to see color changes in the solution during titration, improving the accuracy of the endpoint determination. It enhances the visibility of subtle color changes, ensuring the titration results are more precise and reliable.
Why do you use external indicator in diazotization titration?
external indicator is required in diazotization as to observe the end point of the reaction. internal indicators cannot give the endpoint because they may form complexes which may cause hindrance. for example, in the assay of sulfa drugs, iodine-starch paste is used as external indicator, because if we add iodine paste in the conical flask it will react with the reactants and give the blue-black coloration in the beginning of the actions, which will not tell the end point of the reaction. instead, the iodine-starch paste is applied in a paper, and the compound from the burette is added in small quantities into the sulfa drug solution, and after every few milliliters a drop of solution from the conical flask is dropped on the iodine-starch paste, when there is sudden change in colour, the addition from the burette is stopped. and observations are made.
Why is the outside of the burette wiped with paper towel before titration?
The outside of the burette is wiped with a paper towel before titration to ensure that any liquid droplets on the outer surface do not affect the accuracy of the titration by inadvertently entering the solution being titrated. This helps to prevent contamination and ensure precise measurements are obtained during the titration process.

Would water vapor burn paper if placed over a boiling cup?
I probably wont get hot enough to burn paper if just placed over a cup, A good experiment that you can do is boil some water in a flask. poke a hole through a rubber stopper and place that in the flask. in the rubber stopper hole, Place a Copper tube that is in a coil making sure that some is sticking out a little bit. Place a bunsen burner under the copper coil. when steam starts to come out, place paper in the steam, it should scorch the paper but it will not catch on fire.
What is filtrating?
To use filtration as a method of separating a solid from a liquid, you need the following apparatus: conical flask, filter funnel , filter paper, and a stirring rod. Set the apparatus up, then pour the solution into the funnel paper and stir gently. The stuff left in the paper is called the residue, and the stuff which passes through the paper is called the filtrate. More generally, filtration is the action or process of filtering something.
What is the apparatus required for filtration?
The apparatus required for filtration typically includes a filter paper, a funnel, and a receiving flask or container to collect the filtrate. The filter paper is placed inside the funnel, which is supported above the receiving flask. When the mixture is poured into the funnel, the filter paper allows the liquid to pass through while retaining solid particles. Additional equipment may include a stand or clamp to hold the funnel in place.
How do you separate powdered copper sulphate and powdered chalk?
Well, you need to get a beaker and add water.Then add the powdered chalk and add copper sulphate to the beaker.Then get a conical flask with a funnel and get some filter paper and fold it into a funnel and place it the funnel in the conical flask then mix your solution with a stiring rod and pour down funnel .What you should end up with is copper sulphate with the water in the conical flask and the chalk mix in the filter paper.

What equipment and materials will you use in separating insoluble materials from seawater?
You can filter it off using a sinted glass crucible, fine filter paper, a vacuum pump and a side-arm flask. If you don't have that sort of equipment: a filter funnel, filter paper and a conical flask should do.
What is a Buchner or filter flask and how is it used?
From Wikipedia.com (see Link to the left):A Büchner flask, also known as a vacuum flask, filter flask, side-arm flask or Kitasato flask, is a thick-walled erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck. The short tube and hose barb effectively acts as an adapter over which the end of a thick-walled flexible hose (tubing) can be fitted to form a connection to the flask. The other end of the hose can be connected to source of vacuum such as an aspirator vacuum pump or house vacuum. Preferably this is done through a trap (see below), which is designed to prevent the suckback of water from the aspirator into the Büchner flask.See the Web Links and Related Questions to the left for more information.
