Calcium Carbonate
THE QUESTION !!! A student wanted to find the mass of calcium carbonate in an indigestion tablet. She crushed up a tablet and added an excess of HCL acid (25cm3 of 1.00 mol/dm3). She the titrated the excess against 0.5 mol/dm3 of NaOH requiring 25.8cm3 of the NaOH. Calculate the mass off calcium carbonate in the tablet.
No acid contains calcium carbonate. Calcium carbonate is its own compound that is a base, not an acid. However, the erosion and deposition of calcium carbonate in nature is heavily influenced by carbonic acid.
A calcium carbonate supplement is 40% calcium, which is higher than any other calcium supplement.
base.
The carbonate. Calcium is neutral.

Calcium oxide.
The formula for calcium carbonate is CaCO3, and it has a gram formula mass of 100.09. The formula shows that each formula mass contains one calcium atom, which has a gram atomic mass of 40.08. Therefore, the mass fraction of calcium in calcium carbonate is 40.08/100.09, so that a 500 mg tablet of calcium carbonate contains 200 mg of calcium, to the justified number of significant digits.
44.55 ML solution x 1L/1000ML X 0.448M HCL/1L solution X 1mole CaCO3/2 mole HCL= 0.0099792 M CaCO3 0.0099792 M CaCO3 x 217gCaCO3/1 mole CaCO3= 2.17g CaCO3 X 1000MG/1g=2170 mg of calcium carbonate are in a rolaids tablet?
