Limestone consists mainly of the mineral calcite, CaCO3. The carbonate content of 0.5143 g of powdered limestone was measured by suspending the powder in water, adding 10.00 mL of 1.396 M HCl, and heating to dissolve the solid and expel the CO2: CaCO3(s) + 2H+ ⟶⟶ Ca2+ + CO2↑↑ + H2O The excess acid requied 39.96 mL of 0.1004 M NaOH for complete titration: OH- + H+ ⟶⟶ H2O Find the weight percent of calcite in the limestone.
