Reactions:

CaCO3 + 2HCl → CaCl2 + CO2 + H2O

Mg(OH)2 + 2HCl → MgCl2 + 2H2O

M(CaCO3) = 100 g/mol

M(Mg(OH)2) = 56 g/mol

Two moles of HCl are used for one mole of antacid product in both reactions.

So, to neutralize of two moles of HCl less Mg(OH)2 (56 g) are required as compared to 100 g of CaCO3.

So, milk magnesia is more effective at neutralizing acid per gram of the active ingredient.

A teaspoon of milk of magnesia contains 12.0 mg of magnesium hydroxide. What volume of 0.010 mol/L HCl in a person's stomach would be neutralized by this teaspoon of antacid?

Solution:The balanced chemical equation:Mg(OH)2(s) + 2HCl(aq) = MgCl2(aq) + H2O(l)According to the chemical equation: n[Mg(OH)2]= n(HCl)/2Moles of Mg(OH)2 = n[Mg(OH)2] = Mass of Mg(OH)2 / Molar mass of Mg(OH)2The molar...

A teaspoon of milk of magnesia contains 25.0 mg of magnesium hydroxide, Mg(OH)2. What volume of 0.010 M HCl in a person’s stomach would be neutralized by this teaspoon of antacid?

Solution:The balanced chemical equation:Mg(OH)2 + 2HCl = MgCl2 + 2H2OAccording to the equation: n(Mg(OH)2) = n(HCl)/2Mass of Mg(OH)2 = 25.0 mg = 0.025 gMoles of Mg(OH)2 = Mass of Mg(OH)2...

write a balanced equation for the reaction of the active ingredient in Tums with excess acid.

There are two active components in Tums: magnesium carbonate and calcium carbonate. Normally, they are used to neutralize the main component of gastric acid - hydrochloric acid: MgCO3 + 2HCl...

if the antacid for analysis is known to be Phillips' milk of magnesia the solution does not need to heat but if the sample is Mylanta the solution must be heated

The only sufficient difference in the experimental procedures is if the product of the reactant(s) need to be heated or not. For the Phillips Milk of magnesia, heat is not...

Mg(OH)2 + 2HCl = MgCl2 + 2H2O Assume that a person takes 0.100 g antacid. How many mol of MgCl will be produce from the ingested antacid, assuming all of the antacid undergoes the reaction?

Mg(OH)2 is the antacid; m(Mg(OH)2) = 0.100 g;Molar mass Mr(Mg(OH)2) = Ar(Mg) + 2Ar(O) + 2Ar(H) = 24.305 g/mol + 2*16 g/mol + 2*1 g/mol = 58.305 g/mol.n(Mg(OH)2) = m(Mg(OH)2)/Mr(Mg(OH)2)...
