A 0.5895-g sample of impure magnesium hydroxide is dis- solvedin 100.0 mL of 0.2050 M HCl solution. The excess acid then needs19.85 mL of 0.1020 M NaOH for neutralization. Calculate the percentby mass of magnesium hydroxide in the sample, assuming that it isthe only substance reacting with the HCl solution.

. A 1.248 g limestone rock, which contains CaCO3 and other compounds, is pulverized and treated with 30.00 mL of 1.035 M HCl solution. The excess acid requires 11.56 mL of 1.010 M NaOH for neutralization. Calculate the percent by mass of calcium carbonate in the rock, assuming it is the only substance reacting with the HCl solution.

The active ingredients in a particular antacid tablet are aluminum hydroxide, Al(OH)₃, and magnesium hydroxide, Mg(OH)₂. A 5.00 x 10²mg sample of the active ingredients were dissolved in 50.0 mL of .500 M HCl. The resulting solution, which was still acidic, required 16.5 mL of 0.377 M NaOH for neutralization. What are the mass percentages of Al(OH)₃ and Mg(OH)₂ in the sample?

The active ingredients in a particular antacid tablet are aluminium hydroxide, Al(OH)₃ and magnesium hydroxide, Mg(OH)₂. A 5.00 x 10² mg sample of the active ingredients were dissolved in 50.0 mL of 0.5 M HCl. The resulting solution, which was still acidic, required 16.5 mL of 0.377 M of NaOH for neutralization. What are the mass percentages of Al(OH)₃ and Mg(OH)₂ in the sample?
