Amfani
Potassium hydroxide, wanda aka fi sani da caustic potash ko potash lye, yana samuwa ne a fannoni biyu na masana'antu: tauri da ruwa. Tauri yana bayyana a matsayin fari ko launin toka mai haske, guntu, ko sanduna, yayin da sifar ruwa ruwa ne mai launin rawaya mai haske. Halayen sinadarai nasa sun yi kama da na sodium hydroxide, yana da ƙarfi alkalinity da lalata. Yana narkewa cikin sauƙi a cikin ruwa kuma yana fitar da zafi mai yawa, kuma yana nuna ɗanɗano, ma'ana yana iya shan danshi daga iska da deliquesce cikin sauƙi, kuma yana iya amsawa da carbon dioxide don samar da potassium carbonate. Idan aka narke a cikin ruwa, barasa, ko aka yi masa magani da acid, yana fitar da zafi mai yawa. Maganin 0.1 mol/L yana da pH na 13.5 (anhydrous). Yana da matsakaicin guba, tare da matsakaicin adadin kisa (na baki, bera) na 1230 mg/kg. A halin yanzu, ana amfani da potassium hydroxide galibi don haɗa potassium carbonate, potassium permanganate, da sauransu, kuma ana amfani da shi galibi a masana'antar sinadarai, abinci, magunguna, da noma.
