Difference Between Beaker and Erlenmeyer Flask

Erlenmeyer flasks have a narrow neck over a conical base, while beakers are basically large open-mouthed glass jars with a lip and spout for pouring. ... Volumetric flasks have a flat-bottomed bulb and a long, narrow neck with a hash mark along the side to indicate the point at which the flask is full.

Whats the difference between a beaker and a flask?

Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. ... The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next.

Why use an Erlenmeyer flask instead of a beaker?

The Erlenmeyer flask offers a slight advantage in accuracy due to its tapered sides. The size of the beaker or flask should be chosen to allow for more liquid to be added during the titration process. ... This makes it simpler than subtracting once the titration is complete. There is a valve at the bottom of the burette.

Which is more accurate Erlenmeyer flask or beaker?

The volumetric flask had the lowest percent error (0.3%), so it is the most accurate. The graduated cylinder and beaker were similar in percent error (2.2% and 3.5% respectively). Both were small, so they are fairly accurate. The flask had the highest percent error (17.4%), so it is the least accurate.

What are the similarities and differences between a beaker and a conical flask?

There are several differences between the two common laboratory containers called beakers and flasks. The main difference between beakers and flasks is their shapes. A beaker is a cylinder with a lip for pouring and no lid. Flasks are curved with no lip and have lids.

Why is an Erlenmeyer flask not accurate?

Beakers and Erlenmeyer flasks should not be used to measure volume unless you need only a very crude estimate because their accuracy for volume measurements is so poor. They can hold a much larger volume than any of the other types of glassware, however, which makes them useful for mixing solutions.

What is the purpose of an Erlenmeyer flask?

Erlenmeyer Flask

Used to hold and mix chemicals. The small neck is to facilitate mixing without spilling.

Why titration flask should not be rinsed?

When you're cleaning your glassware, you use water to rinse it off. If the burette is not completely dry by the time you use it, the remaining traces of water on the inside will make your titrant more dilute and thereby change its concentration.

What are characteristics of an Erlenmeyer flask?

Erlenmeyer flasks are recognizable from their basic characteristics: flat bottom, conical body, and long, cylindrical neck. They are named for German chemist Emil Erlenmeyer.

Why do we have to swirl the liquid in the flask?

4.It is important to stir the solution in the flask as you add the titrant from the buret so that you can ensure that everything is mixed together and the reaction is complete.

Why beaker is not accurate?

The volume marks on a beaker are only approximate values, and therefore only provide whole numbers. For example, a 100 mL beaker might only have marks for every 20 mL, so it would be tricky to gauge the exact volume of a liquid sample falling between the 60 mL and 80 mL marks.

How accurate is a beaker?

According to Indigo Instruments, the accuracy of a beaker is about 10 percent. A graduated cylinder is accurate to 1 percent of its full scale.

How precise is a burette?

10 mL burettes are usually graduated each 0.05 mL, while 25 mL and 50 mL burettes are usually graduated each 0.1 mL. That means that 50 mL burettes have the highest resolution. 0.050 mL out of 50 mL is 0.1%, and that's about maximum precision that we can get from volume measurement when using burette.
