Ojiji
Potassium hydroxide, nke a maara dịka caustic potash ma ọ bụ potash lye, dị n'ụdị ụlọ ọrụ abụọ: siri ike na mmiri mmiri. Ụdị siri ike ahụ na-apụta dị ka flakes ọcha ma ọ bụ obere isi awọ, iberibe, ma ọ bụ mkpanaka, ebe ụdị mmiri mmiri ahụ bụ mmiri mmiri odo odo na-acha odo odo. Njirimara kemịkalụ ya yiri nke sodium hydroxide, nwere alkalinity siri ike na corrosion. Ọ na-agbaze ngwa ngwa na mmiri ma na-ewepụta nnukwu okpomọkụ, na-egosipụtakwa deliquescence, nke pụtara na ọ nwere ike ịmịkọrọ mmiri site na ikuku na deliquesce ngwa ngwa, ma nwee ike imeghachi omume na carbon dioxide iji mepụta potassium carbonate. Mgbe a gbazere ya na mmiri, mmanya na-aba n'anya, ma ọ bụ jiri acid gwọọ ya, ọ na-ewepụta nnukwu okpomọkụ. Mmiri 0.1 mol/L nwere pH nke 13.5 (anhydrous). Ọ nwere nsí dị ala, yana oke ọnụọgụ ọnwụ (ọnụ, oke) nke 1230 mg/kg. Ugbu a, a na-ejikarị potassium hydroxide emepụta potassium carbonate, potassium permanganate, wdg, a na-etinyekwa ya na ụlọ ọrụ kemịkalụ, nri, ọgwụ, na ọrụ ugbo.
A na-ejikarị potassium hydroxide eme ihe dị ka ihe e ji emepụta nnu potassium, dị ka potassium permanganate na potassium carbonate. N'ụlọ ọrụ ọgwụ, a na-eji ya emepụta potassium borohydride, Antishutong, silybin, progesterone, na testosterone propionate. N'ụlọ ọrụ ọkụ, a na-eji ya emepụta ncha potassium, batrị alkaline, na ihe ịchọ mma (dị ka ude oyi, ude snow, na shampoo). N'ụlọ ọrụ agba, a na-eji ya emepụta agba vat, dị ka RSN acha anụnụ anụnụ vat.
