Tum-Tum-Tum-Tum-Tums

Formula of tums:
active ingredient calcium carbonate CaCO3 -->Ca(+2)aq + CO(-2)aq

How do tums chemically react with water and stomach acid?
calcium carbonate is not water soluble and breaks down slowly in acid unless broken up.

How many tums are needed to neutralize a can of coke?
