Sample Problem 3.15
Calculating Amounts of Reactants and Products for a Reaction in Solution
PROBLEM:
Specialized cells in the stomach release HCl to aid digestion. If they release too much, the excess can be neutralized with antacids. A common antacid contains magnesium hydroxide, which reacts with the HCl to form water and magnesium chloride solution.
PLAN:
Write a balanced equation for the reaction; find the moles of Mg(OH)2; determine the mole ratio of reactants and products; use moles to convert to molarity.
