Mugadziri Akanaka Mutengo Potassium Hydroxide Cas: 1310-58-3
Potassium Hydroxide: Potassium Hydroxide (Chemical Fomula: Koh, Fomula Kuwanda: 56.11) White Powder kana Flake Solid. Iyo yekunyunguduka ndeye 360 ~ 406 ℃, iyo Boiling ndiyo 1320 ~, density iri, cm (719 ℃). Yakasimba alkaline uye controsive. Zviri nyore kutora unyoro mumhepo uye nemaune, uye kutora carbon dioxide muPotassium carbonate. Nyoro inenge iri munhengo inenge mvura inopisa, 0.9 zvikamu zvinotonhora mvura, 3 zvikamu ethanol uye 2.5 zvikamu glycerol. Kana ikanyungudika mumvura, doro, kana kubatwa neakari, huwandu hombe rekupisa rinogadzirwa. Iyo pH ye 0.1mol / l mhinduro yaive ne1.5. Zvine mwero kuveura, median lethal dire (makonzo, emuromo) 1230mg / kg. Nyoroveswa muEthamol, svutugadzike zvishoma muEtera. Iyo inonyanya kuwanda uye inokanganisa
