Appearance = white to yellow powder or solidCalcium peroxide (CaO2) is a solid
peroxide with a white or yellowish color. For all practical purposes calcium peroxide is insoluble inwater but will dissolve inacid to formhydrogen peroxide . When in contact with water it will immediately begin to decompose releasing oxygen.Applications
Calcium peroxide is manufactured to varying specifications and purity and can be used in different areas of
industry andagriculture . In agriculture it is used as anoxygen fertilizer , and is also used in the presowing treatments ofrice seed . Also, calcium peroxide has found use in theaquaculture industry as it is used to oxygenate and disinfect water, and in the ecological restoration industry as it is used in the treatment of soils. Calcium Peroxide is used in a similar manner tomagnesium peroxide for environmental restoration programs. It is used to restore soil and groundwater contaminated with petroleum hydrocarbons by stimulating aerobic microbial degradation of the contaminants in a process known asEnhanced In-Situ Bioremediation .As a
food additive it has theE number E930 and is used asflour bleaching agent andimproving agent .
