What is the different between conical flask and volumetric flask?
They both do something :)
How do you transfer any remaining solute into a volumetric flask?
To transfer any remaining solute into a volumetric flask, first dissolve the solute in a small amount of solvent in a beaker. Then, rinse the sides of the beaker with more solvent to ensure all the solute is transferred, and finally pour this solution into the volumetric flask and rinse the beaker multiple times to ensure quantitative transfer.
What is an acid burette?
An acid burette is a laboratory glassware instrument used for dispensing precise volumes of acid during titration experiments. It typically has a stopcock at the bottom to control the flow of the acid and a scale to measure the volume of liquid dispensed.
Why sodium hydroxide is dissolved in a little water in a beaker before transferring it into volumetric flask?
The dissolution of sodium hydroxide in water is very exothermic. One might worry the solution may boil out of the volumetric flask and cause a hazardous situation. Volumetric flasks are also fairly thin compared to a beaker and aren't designed to take much heat, if any
Why is a volumetric pipette more accurate than a graduated pipette?
Graduated pipettes are not as accurate as volumetric pipettes, because each graduation line is not individually calibrated, and any imperfection in the internal diameter will have a greater effect on the volume delivered. In volumetric pipettes, the diameter of the pipette where the graduation mark is located is significantly smaller because the majority of its volume is located in the bulb.
What makes a type of glassware more or less accurate?
volumetric flask
Could a 25 ml volumetric flask be replaced by a 25 ml pipette to measure the solution poured into a conical flask for titration?
As the pipette is far more accurate than a flask by a factor 10 to 100 one should NOT use a volumetric flask except for standard volumes over 100 ml.
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.

What is conical flask accuracy?
A conical flask is typically used for holding and mixing liquids in a laboratory setting. Its accuracy in measuring volumes is limited, as it lacks precise calibration markings like those found on a graduated cylinder or volumetric flask. For more accurate volume measurements, a more precise measuring device should be used.
Can a flask perform accurate measurements?
It depends on what flask and what the quality of it is. If there is a hole in the flask, then obviously, no measurements. Most of the time, flasks do NOT give the most accurate measurements. Although, they do give more accurate measurements than a human eyeball and flasks do have their strengths compared to other tools as well.
What instrument is used to find volume of liquid?
measuring cylinder, volumetric flask and so many more

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 happen if you adding water to the titrated substance in the conical flask during the process of titration?
NoUser 1Yes. By adding water to rinse, you will be changing the concentration of the thing you are titrating, and so your calculation will be off. If you have material on the walls of the flask, just gently stir the flask and let the solution in the flask wash anything off the walls.User 2I do not believe this is true. Once you add an amount of reactant into your flask adding more water will not change the number of moles of reactant that are present in the flask. The titrant will react in the mole ratio for that particular reaction so water doesn't play a role. You can rinse the flask and even use water to get part of a drop into your flask for a more accurate titration.User 3No. User 1 means to say that water in the volumetric burette or pipette will effect the concentration of titrant moles. Water in a conical flask will not effect the titre values because the same mole ratios are reacting, and your titre value is measured from the volume remaining in the volumetric burette and not the conical flask. User 2 is correct, although using water to rinse the volumetric burette's contents into the conical flask would adversely effect the results, as volumetric burettes and pipettes are designed to account for the few remaining drops in the instruments. Shaking or tapping the instruments is also a bad idea, as they can easily be broken and doing this would effect your titre values anyway.User 4It will not affect the result at all as long as you use distilled water, as just tap water obviously contains other minerals etc that will affect the results.
How burette is more accurate than measuring cylinder?
burette gives a much finer volume reading than a measuring cylinder and all the chemicals can be placed inside it at the start of the experiment.
Which is more accurate to measure volume of liquids a burette or measuring cylinder?
A burette is generally more accurate for measuring volumes of liquids compared to a measuring cylinder. This is because a burette allows for precise control of liquid delivery and has finer graduations, enabling measurements to the nearest 0.01 mL. In contrast, measuring cylinders have larger increments, making them less precise for small volume measurements. Therefore, for tasks requiring high accuracy, a burette is the preferred choice.
