Which vessel is more appropriate for mixing by swirling a beaker or an erlenmeyer flask?

The Erlenmeyer flask's narrow neck allows more vigorous swirling without as much chance of spilling as with a beaker or other wide mouth vessel.

What is the usage of beaker?
The purpose is to measure liquids and to boil it on your burner because of the big flat bottom and so you can pour the liquid a little more accurately when trying to do like a small drop of something.
What is a beaker used for during an experiment?
It is used a laboratory container and mixing jar
Which one is more accurate erlenmeyer flask or beaker?
Several things make volumetric flasks the most accurate way to measure volumes of liquids. First, they are specially calibrated and tested so that the volume listed is exactly the correct volume, often to within 0.01 mL. Secondly their shape is specially designed for accurate measurement. They have a long narrow neck with a line to mark the correct volume. Because the neck is so skinny, the water level is much more sensitive to the amount of water than if the neck was much wider (like in an erlenmeyer).Note that an erlenmeyer flask is about the worst thing I can think of to measure volumes! Much better than that is a graduated cylinder. A graduated cylinder, while somewhat less accurate than a volumetric flask does have the advantage of being able to measure different volumes, whereas a volumetric flask is designed to measure one and only one volume.
What is convective mixing?
Convective mixing is the entrainment and deepening of the mixed layer in a lake due to heat loss generally in combination with wind forcing. Convective mixing is the entrainment and deepening of the mixed layer in a lake due to heat loss generally in combination with wind forcing.
What is the gradual mixing of substances called?
dilution
What is use of beaker?
A beaker (Berzelius or Erlenmeyer) is used for: - to contain a liquid, or powdered and granulated materials - to be the container for chemical experiments - to be the container for the dissolution of materials - to collect the solution from a distillation apparatus - to contain a substance to be titrated
Is a beaker for heating and mixing substances?
Yes, it is true.
How does using a beaker affect the results in an experiment?
The traditional use of a beaker is to hold liquids. They are usually used in a scientific setting. Being glass, they can reach higher temperatures than plastic, so they are preferable in many science experiments.
Why should you remove the beaker from the balance before mixing the two reactants?
Because, if you mix the two reactants while the beaker is on the balance than the world will explode into a gigillian pieces!!
What is beaker in laboratory?
A beaker is a simple container for stirring, mixing and heating liquids
What is a graduated beaker?
A beaker is a simple container for stirring, mixing and heating liquids commonly used in many laboratories. Beakers are generally cylindricalin shape, with a flat bottom and a lip for pouring.
Why must the stem of the funnel touches the inside surface of the collecting beaker during the filtration?
it's done to minimize the mixing of air into the filtered solution. By touching the stem to the collecting beaker, the solution flows into the beaker smoothly rather than splashing into it.

What is the use and definition of an Erlenmeyer flask?
The triangular shape of the Erlenmeyer flask aids in the mixing of the liquid inside. When you swirl the flask, the liquid moves up the sides without coming out the top. They are used in applications where solutions must be mixed multiple times. When doing a titration analysis, small amounts of reactant are added to a solution, usually until an indicator changes color, and the solution must be mixed after every addition. When making a dilution of a stock solution, the easiest way is to add a measured amount of stock to a measured amount of solvent in an Erlenmeyer and swirl to ensure thorough mixing. Erlenmeyer flasks are often used to heat liquids with a Bunsen burner. For that purpose, the flask is usually placed on a ring held to a ring stand by means of a ring clamp. A wire gauze mesh or pad is usually placed between the ring and the flask.
What are the Laboratory techniques on mixing water and acid?
Mixing water and acid is very exothermic. Potentially enough heat is generated to cause the water to instantly vaporize, which can result in splattering (and messing up any volume calculations you may have already done). For this reason, ALWAYS add acid to water, NOT the other way around. The water acts as a heat sink and can absorb any heat that is generated. For best results, add the acid slowly while gently swirling the flask/beaker of water. You can also submerge the water flask/beaker into an ice bath.
Example of a hypothesis?
let's sayI'm in science , i have beaker A filled with chemicals. And I have beaker B also with chemicals , and myHYPOTHESIS is that when i join them they will create green.-mixing chemicals-my hypothesis was wrong , they turned purple.a hypothesis is a good educated guess at something.
Container used for mixing or heating of chemical solution?
In a chemical plant it would be a blend tank or reactor. In a laboratory it would be a reaction flask or beaker
