Why solutions cannot be stored in volumetric flask?
Volumetric flasks are designed to hold specific volumes of liquid accurately for dilution or mixing purposes. Storing solutions in a volumetric flask can lead to evaporation, contamination, and inaccuracies in concentration due to the narrow neck of the flask making it difficult to access the solution for further use. It is best to store solutions in appropriate containers designed for long-term storage.
What piece of apparatus is used to measure one specific volume over and over?
A volumetric flask is the piece of apparatus used to measure one specific volume repeatedly. It is designed for precise dilutions and preparation of standard solutions, ensuring accuracy in measurements. The flask typically has a narrow neck and a flat bottom, allowing for easy handling and mixing of liquids.
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.
How many moles are present in 21.5 g of NaCl?
A student placed 15.5 g of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100. mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 40.0mL sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100. mL of the final solution?
What would happen if the neck of the sterilized swan-necked flask were broken?
If the neck of a sterilized swan-necked flask were broken, the flask would be exposed to contaminants in the air, negating the purpose of the swan neck design to prevent microbial contamination. This would likely compromise the sterility of the contents in the flask, leading to potential contamination and spoilage of the culture inside.
What is the name for a conical glass flask with a narrow neck and broad base?
Volumetric flask - used to prepare a standard solution in laboratory
Round flask with long neck?
You could be referring to a florence flask or a volumetric flask.See the Related Questions links to the left for more information.
Why do we use a volumetric flask for measuring precise volumes of liquids?
A volumetric flask is used for measuring precise volumes of liquids because it has a narrow neck and a specific volume marking, allowing for accurate and consistent measurements.
What is a volumetric flask and its uses?
A volumetric flask is a piece of laboratory glassware used in analytical chemistry for the preparation of solutions. It is made of glass or plastic and consists of a flat bottomed bulb with a long neck, usually fitted with a stopper. The stopper is normally made in a chemically resistant plastic such as polypropylene rather than glass. The neck has a single ring graduation mark and a label. The label should show the nominal volume, tolerance, calibration temperature, class, relevant manufacturing standard and the manufacturer’s logo. The glass or plastic is generally clear but may be amber colored for handling light sensitive compounds such as silver nitrate or vitamin A.
What is difference between erlenmeyer flask and volumetric flask?
Erlenmeyer flasks have a conical shape with a narrow neck, used for mixing, heating, and storing liquids. Volumetric flasks have a flat bottom with a long neck and a specific volume graduation mark, used for making precise volume measurements and preparing solutions.
Why solutions cannot be stored in volumetric flask?

What is a flask and its uses?
Volumetric flask, also known as measuring flask or graduated flask, is a kind of glassware which is used for accurate dilutions and preparation of standard solutions. Volumetric flasks are usually pear-shaped with a graduation mark on the neck. The mark indicates the volume when the solution reaches there. Volumetric flasks are various in size, but they come in standard size, 10.00 ml, 25.00 ml, 50.00 ml, 100.0 ml, 250.0 ml, 500.0 ml, etc.
What happens when a liquid is poured into a volumetric flask into a beaker?
When a liquid is poured into a volumetric flask, the liquid will fill the flask up to the calibration mark on the neck, ensuring an accurate volume measurement. In a beaker, the liquid will simply fill the beaker without any specific accuracy in volume measurement. Volumetric flasks are designed for precise volume measurements, while beakers are general-purpose containers for holding liquids.
What is the different between conical flask and volumetric flask?
They both do something :)
How do you measure the density of Transformer oil?
to measure density you use a volumetric flask this is a big bottle with a narrow neck there is a mark on the neck with a precise volume fill a 1 liter flask with your oil if it weighs 1Kg the density is 1 kg / liter or 1 gram per cc generally referred to as 1 in liquids or Unity in oil for manometers
Function of flask?
A flask is essentially a bottle. * In a labs, glass flasks (Erlenmeyer, Florence) are used for mixing heating and storing solutions. Sometimes they are graduated to show the volume of material that they contain.* Vacuum flasks are more robist, ususally with a side arm to remove gases * Insulated flasks keep things cold like liquid nitrogen
How do you determine the volume of solution in liters for molarity?
Solutions with known molarity are usually made in volumetric flasks that are calibrated and certificated. So for example I would weigh 58.5 g of NaCl and wash with water into a 1 liter volumetric flask and make exactly to the calibrated mark on the flask neck so I would have exactly 1 liter. My molarity would be exactly 1.00 moles NaCl per liter. Similarly there are 100 ml, 250 ml, 500 ml and other calibrated volumetric flasks so the volume is always exactly known.
