Question

Which gas is used for the preparation of soda water?
A) Carbon monoxide
B) Carbon
C) Sulphur
D) Chlorine
E) Carbon dioxide

Answer 1

The process of formation of soda water is known as carbonation which causes the water to become effervescent. Henry’s Law is used in this process which describes the amount of gas that can be dissolved in the water.

Complete answer:
Carbonated water (also referred to as soda water, soda water, fizzy water, water with gas or (especially within the U.S.) as seltzer or seltzer water) is water containing dissolved CO2 gas, either artificially injected struggling or occurring thanks to natural geological processes. Carbonation causes small bubbles to make, giving the water an effervescent quality. Common forms include sparkling natural drinking water, club soda, and commercially-produced soda water.
For the manufacturing of soda water, the gas used is carbon dioxide. The process in which the soda water is formed is known as carbonation. It is the process which causes the water to become effervescent. Henry’s Law describes the amount of carbon dioxide to be dissolved in the water. To make the maximum amount of carbon dioxide to dissolve through it, water is chilled optimally to just above the freezing point.
Hence, the correct option is (E) .

Note: Natural and made carbonated waters may contain a little amount of common salt, sodium citrate, bicarbonate of soda, potassium acid carbonate, potassium citrate, potassium sulphate, or disodium phosphate, counting on the merchandise. Artesian wells in such places as Mihalkovo in the Bulgarian Rhodope Mountains, Medžitlija in North Macedonia, and most notably in Selters in the German Taunus mountains, manufacture naturally effervescent mineral waters.
