In alkaline tov, KMnO4 yog thawj zaug txo mus rau manganate thiab ces mus rau insoluble manganese dioxide.

KMnO4 ua li cas hauv nruab nrab alkaline?

Nyob hauv nruab nrab alkaline, KMnO4 reacts raws li nram no - 2KMnO4+2KOH →2K2MnO4+H2O+O.

Dab tsi yog dilute alkaline KMnO4 hu ua?

Potassium permanganate yog tus muaj zog oxidizing tus neeg sawv cev uas txhais tau hais tias nws nyiam coj electrons los ntawm lwm yam tshuaj. Nws dissolves nyob rau hauv dej kom muab ntshav daws. Nws muaj qab zib saj thiab tsis muaj ntxhiab tsw. Cov manganese yog nyob rau hauv +7 oxidation xeev. Teb tau tseeb los ntawm Toppr.

Qhov twg hauv qab no tsis oxidized los ntawm alkaline KMnO4?

F− ions tsis tuaj yeem oxidised los ntawm cov oxidising muaj zog xws li KMnO4.

YPuas yog alkaline KMnO4 txo tus neeg sawv cev?

Ua tiav cov kauj ruam los ntawm cov lus teb:

Cov tshuaj no yog muaj zog oxidizing tus neeg sawv cevvim tias cov ntsiab lus ua electronegative ntau dua li cov oxidation xeev ntawm lawv cov atoms nce. Potassium permanganate muaj anion MnO4- nyob rau hauv uas yog vim li cas rau nws muaj zog oxidizing zog.
