VWR® Calcium Carbonate, ≥99%, GPR RECTAPUR® is a precipitated calcium carbonate reagent supplied as a white, odourless powder for general-purpose laboratory and industrial applications. With a minimum assay of 99% and a median particle size of d50 1.0 µm, it is suitable for routine reagent preparation, chemical analysis, formulation work, teaching laboratories, and general research use.
Calcium carbonate is nearly insoluble in water and alcohol but soluble in acids such as acetic acid, hydrochloric acid, and nitric acid, making it useful in neutralisation reactions, buffering-related work, filler studies, and carbonate chemistry applications.
