Question

Which of the following is used in the preparation of aerated water?
A.$CO$
B.$C{O_2}$
C.$S{O_2}$
D.$HCl$

Answer 1

We know that food items are preserved using salts, oils and certain gases. Likewise, drinks and beverages are also preserved using gases. Drinks and beverages exist either in aerated, non-aerated or as carbonated drinks. We must know that the aerated water generally refers to water which is aired or air is added to the water.

Complete step by step answer:
We must need to know that the aerated water is frequently applied to carbonated water.
In the modern world, aerated or carbonated water is made by injecting pressurized carbon dioxide into water. The pressure increases the solubility and allows more carbon dioxide to dissolve than those possible under standard conditions. When the bottle of aerated water is opened, the pressure is released allowing the gas to escape out of the solution, which forms bubbles.
We must remember that the carbonated water is also known as soda water, sparkling water or fizzy water. Many beverages like cokes are also carbonated drinks. Where carbon dioxide gas is dispensed into the liquid. Juices and syrups are non-aerated drinks which don’t require aerating.
Hence, the correct answer to the question is option B carbon dioxide.

Note:
We must remember that various carbonated waters are sold in bottles and cans. While many are produced on demand on a large scale by commercial carbonation systems in bars and restaurants. It can also be made at home using a carbon cartridge. Aeration technique is also used in ponds, lakes and reservoir management to cope up with low oxygen levels or algal blooms. Aeration is done to maintain oxygen level and for oxygenation of ponds, lakes and water reservoirs.
