Peroxides xa mus rau cov tebchaw tsim los ntawm cov pa oxygen thiab lwm cov ntsiab lus, qhov twg oxygen nqa tus nqi ntawm -2. Los ntawm cov tshuaj formula, ob qho tib si peroxides thiab oxides muaj oxygen, tab sis lawv cov nqi ntawm cov pa oxygen txawv. Cov pa oxygen hauv cov oxide muaj nqi ntawm -2, thaum cov pa oxygen hauv cov peroxide muaj nqi ntawm -1.
Peroxide yog hais txog ib qho oxide uas muaj ob lub atoms oxygen, qhov twg cov pa oxygen coj tus nqi ntawm -1. Piv txwv li, hydrogen peroxide, benzoyl peroxide, thiab lwm yam oxides yog tsuas yog siv rau kev npaj ntawm lwm cov tebchaw los yog inorganic cov ntaub ntawv, thaum peroxides thiab oxides yog ob tug sib txawv tebchaw nrog txawv tshuaj zog, qauv, thiab siv.
1. Cov qauv sib txawv: Cov tshuaj lom neeg ntawm ob lub atoms oxygen uas muaj nyob rau hauv peroxide yog so thiab yooj yim tawg dua li cov tshuaj sib txuas ntawm cov pa atoms hauv oxide, yog li qhov decomposition tus nqi ntawm peroxide yog sai dua li cov oxide.
2. Cov khoom siv tshuaj sib txawv: Peroxides muaj cov khoom siv tshuaj lom neeg ntau dua li oxides, yooj yim decomposing los tsim cov dawb radicals, thiab muaj zog oxidizing thiab txo cov khoom. Piv txwv li, hydrogen peroxide tuaj yeem cuam tshuam nrog cov hlau los tsim cov pa oxygen thiab dej. Txawm hais tias lawv txhua tus muaj cov pa oxygen, cov nqi ntawm cov pa oxygen txawv, yog li lawv cov khoom sib txawv. Yog li ntawd, txawm hais tias peroxides thiab oxides muaj qhov sib xws, lawv yog ob qhov sib txawv.
3. Kev siv sib txawv: Peroxides muaj zog oxidizing thiab txo cov khoom thiab siv dav hauv tshuaj dawb, tshuaj tua kab mob, oxidants, thiab lwm yam. Piv txwv li, hlau oxide, zinc oxide, thiab lwm yam.
