Quick Summary

Whiting can refer to two distinct subjects. One is a type of marine food fish, specifically a European fish (Merlangius merlangus) belonging to the cod family, or the silver hake.1

The other meaning of whiting is a fine powder of calcium carbonate (CaCO₃). This white powder is used as a pigment, an extender in putty, and in compounding rubber and coating paper. Calcium carbonate itself is a chemical compound composed of calcium, carbon, and oxygen. It is the primary component of substances like limestone, marble, and chalk. It exists naturally in mineral forms such as calcite, aragonite, and vaterite.23
