Question
1)what is the balanced chemical equation for the complete neutralization of 1 mole of the active ingredient in "Gaviscon" with acid H+ ions?2)what gas is generated when "Alka seltzer II" used to neutralize an acid. Is this same gas generated when "Milk of Magnesia" is used? Explain based on active ingredients.
3)NaHCO3 is one of the oldest antacids used. Use the stoichiometry of the HCl and 5.56mL of 0.100M NaOH was required to titrate the un-neutralized HCl, calculate the actual neutralising capacity of the antacid in mmol H+ per gram 1)what is the balanced chemical equation for the complete neutralization of 1 mole of the active ingredient in "Gaviscon" with acid H+ ions?

Explanation / Answer
1) The active ingredients in Gaviscon is NaHCO3 and CaCO3.
NaHCO3 + CaCO3 + 3H+ -----> Na+ + Ca2+ +2H2O + CO2
Therefore, for 1 mole of active ingredients, 1.5 moles of H+ ions are required to completely neutralize
2) One of the active ingredients in Alka Seltzer is NaHCO3, which produces CO2 gas when neutralized by an acid. Milk of Magnesia is a suspension of Mg(OH)2, which doesnt produce any gas when neutralized by an acid.
3) Question is not properly phrased and more information is needed.
