A tablet containing calcium carbonate and fillers with a mass of 1.631 g was dissolved in...
A tablet containing calcium carbonate and fillers with a mass of 1.631 g was dissolved in HCl. After the fillers were filtered out, the HCl was neutralized by adding sodium carbonate. The resulting precipitate was pure calcium carbonate (with the fillers removed). The solid calcium carbonate was collected on a watch glass that had a mass of 46.719 g when empty. After the calcium carbonate had been allowed to dry, the mass of the watch glass plus product was found...

A antacid tablet is 85% calcium carbonate by mass. The tablet is fully dissolved into 180.0mL of 0.170 M HCL, leaving excess HCL. A volume of 19.00 mL of 0.245 M KOH is needed to neutralize the remaining acid. What is the full molecular equations for both neutralization reactions occurring? What is the original mass of the tablet used?

The active component in one type of calcium dietary supplement is calcium carbonate. A 1.2450-g tablet of the supplement is added to 50.00 mL of 0.5000 M HCl (aq) and allowed to react. After completion of the reaction, the excess HCl (aq) requires 40.65 mL of 0.2535 M NaOH (aq) for its titration to the equivalence point. What is the calcium content of the tablet, expressed in milligrams of Ca^2+? m_ca^2+ = mg

An antacid tablet weighing 0.928 g contained calcium carbonate as the active ingredient, in addition to an inert binder. When an acid solution weighing 56.424 g was added to the tablet, carbon dioxide gas was released, producing a fizz. The resulting solution weighed 57.120 g. How many grams of carbon dioxide were produced?

A tablet weighing 2.074 g and containing aluminium salts was dissolved and diluted to 100.0 mL in a volumetric flask. A 25.00 mL aliquot was removed and treated with enough ammonia to precipitate the aluminium (Al) present as aluminium hydroxide (Al(OH)3). After ignition at 800 oC, this precipitate was converted to aluminium oxide (Al2O3) weighed 0.1967 g. Calculate the Al% in the tablet.
