Suppose you are analyzing an antacid that contains Mg(OH)2 and Al(OH)3
in a 1:1 molar ratio. The antacid was neutralized with an excess of 0.500 M HCl, and the excess HCl was then back titrated with 0.500 M NaOH. The following data was obtained:
Volume of 0.500 M HCl utilized: 38.25 mL
Volume of 0.500 M NaOH utilized: 3.60 mL
Calculate the masses of Mg(OH)2 and Al(OH)3 contained in the antacid.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
