Mawu Oyamba

Amasungunuka m'madzi ndi mowa, osasungunuka mu ether, benzene, chloroform ndi carbon disulfide, ndipo amayamwa madzi mumlengalenga mosavuta. Ili ndi kukoma kokoma kofunda. Imatha kuyamwa chinyezi kuchokera mumlengalenga, komanso hydrogen sulfide, hydrogen cyanide ndi sulfure dioxide. Osalowerera ku litmus. Kwa nthawi yayitali pa kutentha kochepa kwa 0 ℃, ma okosijeni amphamvu monga chromium trioxide, potaziyamu chlorate, ndi potaziyamu permanganate angayambitse kuyaka ndi kuphulika. Zitha kukhala zosagwirizana ndi madzi ndi ethanol, gawo limodzi la mankhwalawa limatha kusungunuka m'magawo 11 a ethyl acetate, pafupifupi magawo 500 a ether, osasungunuka mu chloroform, carbon tetrachloride, petroleum ether ndi mafuta. Mlingo wapakati wakupha (khoswe, pakamwa)> 20ml/kg. Zimakwiyitsa.
