Homework Help: Chemistry

Posted by Jim on Tuesday, April 2, 2013 at 9:54pm.

Some antacid tablets actually contain a mixture of calcium carbonate and magnesium hydroxide (though
they usually have the same “strength” as those that only contain CaCO3). If this had been the case for the
antacid you tested, but you still assumed it only contained CaCO3, how would this have affected each of the
following (too high, too low, or no effect)? Explain.
a) Moles of HCl neutralized by the antacid
b) Mass percentage of CaCO3 in tablet.
