Cr + hcl reaction

WebCrCl 2 is produced by reducing chromium (III) chloride either with hydrogen at 500 °C: 2 CrCl 3 + H 2 → 2 CrCl 2 + 2 HCl or by electrolysis. On the laboratory scale, LiAlH 4, zinc, and related reductants produce chromous chloride from chromium (III) precursors: 4 CrCl 3 + LiAlH 4 → 4 CrCl 2 + LiCl + AlCl 3 + 2 H 2 2 CrCl 3 + Zn → 2 CrCl 2 + ZnCl 2
