Question

Rolaids consumes 47 times its weight in excess stomach acid. Can this be tested using quantitative measurements?

Answer 1

First, one must wonder what the phrase means; i.e., is that 47 times the weight of the active ingredients or the weight of one tablet, or the weight of a spoon (of the liquid stuff if they still make that). At any rate, it probably could be tested by titrating with a base or adding a tablet to an excess of standard acid and back titrating the excess acid with standard base.

Answer 2

Significantly, if stomach acid is very dilute (excess acid), then its weight will include the solvent the acid is in. Of course it would be easy to consume 1000 times its weight if the "excess " acid were very dilute. One is not neutralizing stomach acid, just the "excess".
