What is the empirical formula of the chloride?

Chloride/Formula

The chemical formula for an ionic compound such as KCl is always the same as its empirical formula. We can determine the empirical formula for potassium chloride by using the charges on the ions. Potassium ions have a 1+ charge, and the formula K+ , and chloride ions have a 1− charge, and the formula Cl− .Feb 6, 2016
