Isticmaalka
Potassium hydroxide, oo loo yaqaan caustic potash ama potash lye, waxay inta badan ku jirtaa laba qaab oo warshadeed: adag iyo dareere. Qaabka adag wuxuu u muuqdaa jajab cad ama cawl khafiif ah, jajabyo, ama ulo, halka qaabka dareeruhu yahay dareere huruud khafiif ah. Sifooyinka kiimikada waxay la mid yihiin kuwa sodium hydroxide, oo leh alkalinity xooggan iyo daxal. Si fudud ayuu ugu milmi karaa biyaha wuxuuna sii daayaa kuleyl badan, sidoo kale wuxuu muujinayaa deliquescence, taasoo la macno ah inay si fudud u nuugi karto qoyaanka hawada iyo deliquescce, waxayna la falgeli kartaa kaarboon laba ogsaydh si ay u sameyso potassium carbonate. Marka lagu milmo biyaha, khamriga, ama lagu daaweeyo aashitada, waxay sii daaysaa kuleyl badan. Xalka 0.1 mol/L wuxuu leeyahay pH ah 13.5 (aan biyo lahayn). Waxay leedahay sun dhexdhexaad ah, iyadoo leh qiyaas dhexdhexaad ah oo dilaa ah (afka, jiirka) oo ah 1230 mg/kg. Waqtigan xaadirka ah, potassium hydroxide waxaa inta badan loo isticmaalaa in lagu sameeyo potassium carbonate, potassium permanganate, iwm., waxaana inta badan lagu dabaqaa warshadaha kiimikada, cuntada, dawooyinka, iyo beeraha.
Potassium hydroxide waxaa inta badan loo isticmaalaa sidii walxo ceeriin ah oo loogu talagalay soo saarista cusbada potassium, sida potassium permanganate iyo potassium carbonate. Warshadaha dawooyinka, waxaa loo isticmaalaa in lagu soo saaro potassium borohydride, Antishutong, silybin, progesterone, iyo testosterone propionate. Warshadaha iftiinka, waxaa loo isticmaalaa in lagu soo saaro saabuunta potassium, baytariyada alkaline, iyo qurxinta (sida kareemka qabow, kareemka barafka, iyo shaambo). Warshadaha rinjiga, waxaa loo isticmaalaa in lagu soo saaro rinjiyeyaasha vaat-ka, sida RSN buluugga vaat-ka. Warshadaha electrochemical-ka, waxaa loo isticmaalaa electroplating, xardho, iwm. Warshadaha dharka, waxaa loo isticmaalaa daabacaadda, rinjiyeynta, cadaynta, iyo mercerizing, waxaana sidoo kale si weyn loogu isticmaalaa sidii walxo ceeriin ah oo ugu weyn ee lagu soo saaro fiilooyinka macmalka ah iyo fiilooyinka polyester-ka. Intaa waxaa dheer, waxaa sidoo kale loo isticmaalaa wakiilada kuleylinta birta iyo xoqidda maqaarka, iyo codsiyada kale.
