Question

State why a round bottom flask is preferred to a flat bottom flask during preparations of gases in the laboratory?

Answer 1

Hint:We know Round-bottom flasks are styles of flasks having spherical bottoms used as laboratory glassware, largely for chemical or organic chemistry work they're generally made from glass for chemical inertness; and in trendy days, they are typically made of heat-resistant salt glass. There’s a minimum of one cannular section referred to as the neck with a gap at the tip. 2 or three-necked flasks are common as well. Spherical bottom flasks are available in several sizes, from five mil to twenty L, with the sizes usually inscribed on the glass. In pilot plants even larger flasks are encountered.

Complete step by step answer:
Now we discuss about why we use the round bottom flask in laboratory as,
-To find Heating and/or boiling of liquid.
-To Distillation
-As a distilling flask in Rotary evaporators.
- To Storage of the culture media.
We must remember that the spherical bottoms on these varieties of flasks enable a lot of uniform heating and/or boiling of liquid. Thus, round-bottomed flasks are engaged in applications everywhere the contents are heated or boiled. Thus RB flasks are used in the lab to prepare gases.
Round-bottomed flasks are utilized in distillation by chemists as distilling flasks and receiving flasks for the liquid. One-neck round-bottom flasks are used because the distilling flasks in rotary evaporators. This flask form is additionally more immune to fracturing below vacuum, as a sphere a lot of equally distributes stress across its surface. Therefore, we use a round bottom flask in the laboratory. The image of round bottom flask is given below as,

Note:
Now we see the various apparatus used in chemical laboratories.
-Glass tubes are used for heating chemicals and finding out reactions in chemical solutions.
Boiling tube is a proof against chemicals and used for special purposes. It's a product of Pyrex.
-Beaker: it's used for holding running and mixture solutions.
Spherical bottom flask: In preparation of gases, wherever heating is required. As the flask is round bottomed, heat is consistently circulated throughout on heating.
-Retort: For effecting distillation experiments that embody distillation of acids. Across its surface.
