Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa) | Infobox references | IR spectrum of Copper(I) chloride Copper(I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl. The substance is a white solid sparingly soluble in water, but very soluble in concentrated hydrochloric acid. Impure samples appear green due to the presence of copper(II) chloride.[2] Contents [hide] * 1 History * 2 Chemical
