Are the bubbles in a soft-drink carbon dioxide?

Answer 1

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.

Answer 2

Yes, the bubbles in a soft drink are primarily carbon dioxide gas. When carbon dioxide is dissolved in the liquid under pressure, it forms bubbles when the pressure is released, such as when you open the bottle or can.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
