The strong reducing agent chromium(II) chloride reacted rapidly in molten lithium nitrate-potassium nitrate, at or above the melting point of the eutectic, initially forming a dark-brown-black solution [probably containing chromium(III) and chromium(VI)] and gaseous nitrogen dioxide, but at 200�C giving a green precipitate (Cr2O3) and an orange solution of dichromate. Above 450�C, a further slow reaction converted both compounds into a yellow solution of chromate(VI) containing nitrite partly formed by thermal decomposition of the nitrate.
