This will lead us no where. Never has an endorsed chemistry book mentioned carbonic acid nor do we need to know about its chemistry. Like I said, chances of you having carbonic acid in your mouth are slim to none. (the reaction is very slow and you need an enzyme to make CO2 react with H2O).Tell me about it, I frequently use concepts of Bio in Chemistry (and vice versa), as well as using concepts of physics in maths (and vice versa).
But my argument still stands: when CIE sets questions they consider all the possible responses. Wouldn't they be aware of the fact that there is a probability that some candidates may think in terms of carbonic acid?
Which brings me to my next point: if what has been said above is true, then my theory of CaCO3 is false.
So what is the correct answer.
And again, the syllabus does not assume you know Bio, so stop explaining in those terms. I don't care if lactic acid is present in your buccal cavity; for all I know there could be traces of carbonic acid in the food we eat, that ever occur to you?
Therefore, by intuitively considering the basic mineral and organic acids we come across in our course, 3 is not true.
So unless you come up with a more valid point to defend the flimsy carbonic acid argument, any discussion will be futile.
