Answer:The calcium carbonate is ACS reagent grade with an assay of at least 99.0%.
Answer:This configuration contains 500 g.
Answer:The molecular formula is CaCO₃.
Calcium carbonate is supplied as an ACS-reagent-grade powder with an assay of at least 99.0%. This configuration contains 500 g. The material has the formula CaCO₃, a molecular weight of 100.09 g/mol, and CAS number 471-34-1. Calcium carbonate is used in analytical chemistry, buffer and neutralization studies, preparation of calcium-containing solutions, precipitation experiments, materials research, and general inorganic laboratory work. Its defined ACS reagent specification makes it suitable for controlled laboratory procedures that require documented chemical purity. Because calcium carbonate has limited solubility in water and reacts with acids to release carbon dioxide, experimental preparation conditions should be selected to match the intended analytical or formulation workflow.
