oxidation oksidlanish– oq, kristalli, suvda eriydigan, zaharli kislota, h 2 c 2 o 4 ⋅ 2h 2 o, birinchi o'rim-yig'im odmali turlarining sharbatida kashf etilgan va uglerod oksidini natriy gidroksidi yoki ma'lum karbongidrat bilan kislotalar yoki gidroksidi: asosan, sayqallash uchun, tozalash vositasi sifatida va laboratoriya reagenti sifatida ishlatiladi.
oxalic acid– a white, crystalline, water-soluble, poisonous acid, h 2 c 2 o 4 ⋅2h 2 o, first discovered in the juice of the wood sorrel species of oxalis and obtained by reacting carbon monoxide with sodium hydroxide or certain carbohydrates with acids or alkalis: used chiefly for bleaching, as a cleanser, and as a laboratory reagent.
ozon - kislorodning o3 formasi, u o'ziga xos hid bilan zaif xlorli, ya'ni elektr uchqun yoki ultrabinafsha nuri havo yoki kislorod orqali yuborilganda hosil bo'lganligini ko'rsatadi. atmosferada, ayniqsa momaqaldiroqdan so'ng, kuchli miqdordagi oksidlovchi vosita bo'lib, u biologik jihatdan korroziy bo'lib, juda oz miqdorda bo'ladi. Yuqori atmosferada u ultrabinafshacha nurlarini emiradi, shu bilan ular yer yuzasiga etib bormaslikka to'sqinlik qiladi. oqartirish, suvni sterilizatsiya qilish va boshqalar uchun ishlatiladi.		ozone– a form of oxygen, o 3 , with a peculiar odor suggesting that of weak chlorine, produced when an electric spark or ultraviolet light is passed through air or oxygen. it is found in the atmosphere in minute quantities, especially after a thunderstorm, is a powerful oxidizing agent, and is thus biologically corrosive. In the upper atmosphere, it absorbs ultraviolet rays, thereby preventing them from reaching the surface of the earth. it is used for bleaching, sterilizing water, etc.
