The pH of the human stomach is about 2.5, meaning the concentration of hydrogen ions, H+in the stomach is 3.2×10−3 mol/L. The average volume of fluid in a human stomach (when empty of food or drink) is 68 mL. What mass of sodium bicarbonate (molecular formula NaHCO3 ) is requires to neutralize 50% of the H+ ions in an average stomach? The relevant chemical reaction is the acid-base reaction: NaHCO3+H+…Na++CO2+H2O
