Activity 2 1/20/11 Antiacids

Write the formula for Tums? How does Tums chemically react with water and stomach acid?
CaCO3--> Ca+2 + CO3-2

CO3-2 + H+ --> HCO3- + H+ --> H2CO3 <---> H2O + CO2


How many Tums are needed to neutralize a can of coke?
I tried Tums to neutralize a shot of lemon juice and it took 3 Tums to get it at a pH level of 7. I understand that coke does not have the pH level as lemon juice but I believe it would take probably around 5-7 tums to neutralize a whole can of coke.
