Limestone is therefore an essential part of the batch. However, limestone comes in two basic types: high calcium and dolomitic. The difference between the two relates to the relative magnesium (Mg) content. High-calcium limestone is almost entirely CaCO 3 with 1%—3% impurities.
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long …

CALCULATIONS AND ANALYSIS. Calculate the mass of the dried precipitate, CaC 2 O 4 •H 2 O. ; Calculate the moles of CaC 2 O 4 •H 2 O you produced.; Since each molecule of CaC 2 O 4 •H 2 O contains one atom of calcium, the moles of calcium contained in your sample of limestone equals the moles of CaC 2 O 4 •H 2 O produced. Use this fact to …

Recognition of limestone Limestone can be recognized easily thanks to its effervescent reaction with hydrochloric acid (HCl). Calcite and aragonite, indeed, react with HCl diluted in water at 10% producing CO 2, according to the reaction:. CaCO 3 +2HCl⇌ CO 2 + H 2 O+CaCl 2. Dolomite also reacts with HCl but at such low dilution (10%), the reaction is …
