What is the function of a flask?
Flasks can be used for making solutions or for holding, containing, collecting, or sometimes volumetrically measuring chemicals, samples, solutions, etc. for chemical reactions or other processes such as mixing, heating, cooling, dissolving, precipitation, boiling (as in distillation), or analysis.
Why is a volumetric flask used in titration?
Volumetric flask is used to dilute original sample to known volume, so it is paramount that it contains exact volume. Burette is used to add titrant to the titrated solution and it has a scale on the side, so that you can precisely measure volume of the added solution.
How the design of volumetric flask helps to perform this function?
The volumetric flask is used for measuring accurate volumes of liquid materials for laboratory experiments. Volumetric flasks are calibrated (standardized) to particular volumes. This allows scientists to know exactly how much liquid is contained in a specific flask when filled.
What is the function of volumetric?
A volumetric flask is used to measure very precisely one specific volume of liquid (100 mL, 250 mL, etc., depending on which flask you use). This flask is used to accurately prepare a solution of known concentration.
What is the function of reagent bottle?
Reagent bottles, also known as media bottles or graduated bottles, are containers made of glass, plastic, borosilicate or related substances, and topped by special caps or stoppers. They are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves.
Why use a volumetric flask instead of a graduated cylinder?
Graduated cylinders are generally more accurate and precise than laboratory flasks and beakers, but they should not be used to perform volumetric analysis; volumetric glassware, such as a volumetric flask or volumetric pipette, should be used, as it is even more accurate and precise.
What are the advantages of using a volumetric flask?
Volumetric flasks are used to prepare the solutions of different concentrations in which a measured volume of a chemical substance is added and diluted to the mark. The reading of the meniscus is easier in this case and liquid does not spill. It provides the accurate results than the beakers and measuring cylinders.
What is the function of funnel in laboratory?
Laboratory funnels are used to channel liquids or fine-grained chemicals (powders) into labware with a narrow neck or opening. Often, they are made of plastic such as polypropylene.
