Question

Soda water is a solution of carbon dioxide in water. This solution is composed of a -

A. liquid solute in a gaseous solvent

B. liquid solute in a liquid solvent

Answer 1

Unless this is a meant to be a tricky question...

Well, quick answer is B. carbon dioxide reacts with water unlike oxygen. It gets converted into carbonic acid, which, theoretically is a liquid. So, it is liquid in liquid. For a five hundred dollars, that is my final answer (ever watched who wants to be a millioner?).

But, remember, if you can convince me that carbonic acid can be seen as still CO2 molecules (I just can't see it that way), then the answer can be A (solute and solvent definitions assume solvent is higher in volume but if this was for a million dollars, I would think about this answer also, pretty hard). And reading the previous answer, if you still think it is gaseous CO2 and don't like option A, then, yes, is none of the above, and it is gas in liquid.

But I like my odds when I say the right answer is B. Next question for a thousand dollars?

Answer 2

A

Answer 3

Neither.  It is a gaseous solute in a liquid solvent.

Solute: a substance that is dissolved in another substance.

Solvent: a substance in which a solute is dissolved.
