The chemical mechanism of cytological fixation by anionic chromium reagents remains to be elucidated. Oxidative reactions do occur. Probably more important are

Typically, it is employed with additives that affect the plating process but do not react with the trioxide. Chromic acid lotion is the laboratory commonly used

Chromium trioxide (as flakes or crystals) and the soluble form as chromic acid are used in preparing and making additions to plating solutions,. A detailed study is made of the chromic acid plating solution and of the con- ditions for its preferable to make the substitution initially rather than to wait for.
