CrO3H2SO4
CrO3H2SO4 is an adduct formed from chromium trioxide (CrO3) and sulfuric acid (H2SO4). It is often described by the formula CrO3·H2SO4 and is encountered as a crystalline solid that can be prepared by combining CrO3 with concentrated sulfuric acid at low temperature.
The compound is typically made by adding CrO3 to cold, concentrated H2SO4 and allowing the mixture to
CrO3H2SO4 is a strong oxidizing agent and is highly reactive in concentrated sulfuric acid. It is hygroscopic
In practical use, the CrO3–H2SO4 adduct serves as a source of chromium trioxide in highly acidic environments
Safety: Chromium(VI) compounds are toxic and carcinogenic. CrO3 and its sulfuric acid adduct are strong oxidizers
