Question

Compare and contrast the functions of each of the following types of flasks: filter, Erlenmeyer, volumetric. (Site 1)

Answer 1

See Below

Step-by-step explanation:

The filter flask is an Erlenmeyer flask with a side-arm adapter. This arm allows a scientist to remove unwanted impurities from solids, liquids, or gases in a chemistry experiment. Ultimately, it allows the fluid, or filtrate, to pass through, but stops the solid particles in the process. The Erlenmeyer flask is designed with a flat bottom so it can be used to either boil a liquid or allow a liquid to form condensation. This flask allows a laboratory technician to stir or heat a solution without losing any liquid by placing a stopper in the neck. Lastly, volumetric flasks are used for creating solutions. With their long, narrow neck and flat-bottom, these flasks have a number of advantages and disadvantages. Their specific set of measurements provides a scientist great accuracy. A scientist can use this flask to create solutions, when a solute is mixed with a solvent. It can also be used for dilutions, when a liquid is made thinner by adding water or another solvent. However, because the neck of the flask is so narrow, it can be difficult to pour the measured liquid out of the flask if the scientist over-poured the measurement.

Answer 2

Step-by-step explanation:

1. A filter flask is made up of heavy, transparent glass and suction pump at one side. This kind of flask is used for filtering or distillation of substances and is not the best option for measuring as it is not accurate.

2. An Erlenmeyer flask is a conical flask that is best suitable for titration and for storing chemicals.

3. Volumetric flasks are the best kinds for preparing accurate volumes. They are used for making accurate measurements of solutions.
