Ozone nkịtị Njirimara:
Ozone (O3), a makwaara dị ka superoxide, bụ ihe allotrope nke oxygen (O2), nke bụ a gas na a "pụrụ iche isi" na nkịtị okpomọkụ. Ozone na tumadi na-ekesa na stratospheric ikuku na a elu nke 10 na 50 km. Na nkịtị okpomọkụ ma na nsogbu, ala ịta nke ozone bụ a colorless gas, mgbe ịta esịmde 15%, ọ na-egosi a acha anụnụ anụnụ na agba.
Ozone chemical Njirimara:
Ozone bụ na-ejighị n'aka, bụ ọkara ndụ-nke decomposition bụ banyere 20 ka 30 nkeji. Dị ka okpomọkụ na-abawanye, na decomposition ọnụego na-abawanye. Mgbe okpomọkụ karịa 100 ° C, na decomposition bụ nnọọ ike. Mgbe okpomọkụ esịmde 270 ° C, ọ nwere ike converted n'ime oxygen ozugbo. Ozone erekasịchaala ngwa ngwa na mmiri karịa na ikuku. Na mmiri nwere adịghị, ozone nwere ike ngwa ngwa ghoro oxygen.
Ozone nwere ike oxidizing ike, nke bụ naanị ala karịa fluorine. Nke a ihe onwunwe na-bụ-eji na ya ngwa. Ozone akwado combustion. Mgbe combustibles na-etinye n'ime ozone gas ihere, combustion ọzọ bụ sie ike karịa na oxygen.

Toxicity na corrosivity
Ozone bụ a na-emerụ gas. Mgbe ịta bụ 6,25 × 10-6mol / L (0.3mg / L), o nwere a na-akpali akpali mmetụta na anya, imi na akpịrị.
