(C) When an acidified solution of dichromate (chromic acid) is treated with hydrogen peroxide $(H_2O_2)$,a deep blue colored compound,chromium pentoxide $(CrO_5)$,is formed.The chemical reaction is as follows:$K_2Cr_2O_7 + H_2SO_4 + 4H_2O_2 	o K_2SO_4 + 2CrO_5 + 5H_2O$$CrO_5$ is an unstable compound that decomposes to form $Cr^{3+}$ ions in acidic medium.
