My word...........


The carbonation in soft drink is #"carbon dioxide"#, and when you pop the cap the solution, the coke degases. When you bottle beer or ginger beer at home, just before you cap the bottle, you place a teaspoon of sugar in the bottle. With the residue of yeast, the sugar ferments according to the equation:

#C_6H_12O_6(aq) +6O_2(g) rarr 6CO_2(aq) + 6H_2O(l)#

So carbon dioxide is certainly a solute in soft-drinks, in beers, and in champagne.
