A mixture of bases can sometimes be the active ingredientin antacid tablets. If 0.4826 g of a mixture of Al(OH)₃ and Mg(OH)₂ is neutralized with 17.30 mL of 1.000 MHNO₃, what is the mass % of Al(OH)₃ in the mixture?
Referring back to the titration experiments you completed this semester for Experiment #6 (Volumetric Analysis), suppose you were to use 0.50 M potassium hydroxide as the base instead of 0.50 M sodium hydroxide. How would this affect the results of the experiment? O Less base would be required because the stoichiometry of potassium hydroxide reacting with hydrochloric acid is different. The results would be the same because the molarity of the base is unchanged O The results would change because potassium hydroxide is elementally different from sodium hydroxide. O Potassium hydroxide would react with the hydrochloric acid at a different pH.

Strong acid-base reactions are a subcategory of double displacement reactions. The hydrogen ion of the acid "switches places" with the cation of the base, while the hydroxide ion of the base "switches places" with the anion of the acid. 1.
