Why was the conical flask not washed with the alkali solution it was going to contain?
The conical flask was not washed with the alkali solution it was going to contain because any leftover residue or impurities on the flask could contaminate the alkali solution, affecting the accuracy of the experiment or leading to unwanted reactions. Washing the flask with the solution beforehand would also dilute the solution and affect the concentration needed for the experiment.
What if three identical flasks contain three different gases at stp flask a contains ch4 flask b contains CO2 flask c contains n2 which flask contains the largest number of molecules?
Flask A containing CH4 would have the largest number of molecules because all the gases are at STP (Standard Temperature and Pressure), so they will occupy the same volume. Since CH4 has the lowest molar mass among the gases given, it will have the highest number of molecules in the flask.
What is titration flask used for?
A titration flask is used in the laboratory to hold and contain the solution being titrated. It typically has a narrow neck and a stopcock at the bottom to control the release of the titrant into the reaction mixture during the titration process.
What is another word for triangular flask?
Another word for a triangular flask is a conical flask.
How would I calculate the mass of air in an empty flask?
From the volume of the flask, and the density of air under the conditions in the room, you can calculate the mass of air. The density of air varies with pressure, temperature, humidity, etc. At sea level and at 15 °C air has a density of approximately 0.001225 g/ml, so under these conditions, a liter flask would contain (1000 ml)(0.001225 g/ml) = 1.225 g of air.
What is a E flask used for?
The Erlenmeyer flask is used for titrations, to contain the solution from a filtration, to contain liquids, to make chemical reactions etc.
What is the use of the flask in the laboratory?
Laboratory flask of different types are designed to contain liquids in larger volumes.
What the function of a florence flask?
Uses of the Florence flask: - to contain liquids - to boil liquids - to realize chemical reactions
What is function of the volumetric flask?
A volumetric flask is used to contain a specific volume of liquid. It is generally used in chemistry.
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 was the conical flask not washed with the alkali solution it was going to contain?
The conical flask was not washed with the alkali solution it was going to contain because any leftover residue or impurities on the flask could contaminate the alkali solution, affecting the accuracy of the experiment or leading to unwanted reactions. Washing the flask with the solution beforehand would also dilute the solution and affect the concentration needed for the experiment.
What is flask and its uses?
Erlenmeyer flask is a conical flask made from glass or plastic, sometimes graduated or with a stopcock; uses: - to contain liquids or powders - to realize chemical reactions - it is the preferred flask for titration - heating of liquids (only in Pyrex glass) See also the link below.
What is an aryballos?
An aryballos is a small flask used, in Ancient Greece, to contain perfume or oil.

What is a flask used for?
AnswerA flask is a container for storing or carrying liquid.It also keeps the liquid at the same temparature over a number of hours. A flask is nominally used for carrying liquids in it and usually of the alcoholic nature, and is usually referred to as a hip flask as it is carried in a pocket either the front or back.
Function of round bottom flask?
MY ANSWER:A glass flask used in a laboratory for holding chemical liquids and solutions, which has a spherical shape for uniform heating, and one or more long cylindrical necks.
