  1. A Rolaids tablet has 550 mg of calcium carbonate and 110 mg of magnesium hydroxide.

a) Write the two neutralization reactions with stomach acid (assume HCl, don’t combine reactions)

 

 

 

 

 

b) If the acid concentration is 4.0 x 10‒ 2 M, what volume of stomach acid will be neutralized by each component?

 

 

 

 

 

 

 

 

c) How many Rolaids tablets would be required to neutralize the stomach acid in a typical human stomach (one liter).  What assumptions are implicitly made about the stomach and contents, and is that justified?  Is there information available for a better estimate?
