The active ingredients in a particular antacid tablet are aluminum hydroxide Al(OH)3, magnesium hydroxide Mg(OH)2 and an inert "binder". A 500 mg sample of the active ingredients was dissolved in 50.0mL of 0.500 M HCl. The resulting solution, which was still acidic required 30.9 mL of 0.255M NaOH for neutralization.
(a) Calculate the number of OH ion moles in the antacid tablet.
(b) If the antacid tablet contains 5.0% (mass) of the inert "binder" , how many milligrams of aluminum hydroxide Al(OH)3 and, how many milligrams of magnesium hydroxide Mg(OH)2 does the tablet contain?

QUESTION 10 Magnesium hydroxide, aluminum hydroxide and calcium hydroxide are the active ingredients in many antacids. How do antacids work to relieve acid indigestion caused by stomach HCI? To answer this question, you will need to complete the neutralization equations for each base when they react with HCl, include both the original equation and the equation after dissociating the ions, remember that water doesn't dissociate! I know it is annoying but you must use superscripts and subscripts here as well...
