ʻAno: Pauka keʻokeʻo a keʻokeʻo paha/paʻa kristal
He paʻakai waiwai i ka iodine ka Potassium iodate me ke ʻano KIO3. I nā aniau wela a me ka pulu, ua hydrolyzed ka mahu iodine ma muli o ka hygroscopicity o ka potassium iodide. Ke hoʻohālikelike ʻia me ka potassium iodide, ʻoi aku ka paʻa o ka potassium iodate a he lōʻihi kona ola mālama. He mea pale ikaika ia i ka lawe ʻana o ka iodine radioactive e ka thyroid gland.
Nā Waiwai Huahana
He kristal monoclinic kala ʻole a i ʻole ka pauka kristal keʻokeʻo ka Potassium iodate. ʻAʻohe ʻala. Hoʻoheheʻe ʻia i ka wai, ka waikawa dilute, ethylenediamine, ethanolamine, a me nā hopena wai potassium iodide; hoʻoheheʻe iki ʻia i loko o ka sulfur dioxide wai; hoʻoheheʻe ʻole ʻia i loko o nā ʻalekohol a me ka ammonia.
Nā kristal kala ʻole a pauka keʻokeʻo paha; ʻano monoclinic; nui ka nui 3.90 g/cm3; paʻa i nā mahana maʻamau; heheʻe ma 560°C me ka decompo-sition hapa, e hoʻokuʻu ana i ka oxygen; hoʻoheheʻe iki ʻia i ka wai anuanu; 4.74 g/100mL ma 0°C; ʻoi aku ka nui o ka hoʻoheheʻe ʻia i ka wai e paila ana 32.3 g/100mL ma 100°C; hoʻoheheʻe ʻia i loko o ka hopena potassium iodide; hoʻoheheʻe ʻole ʻia i ka waiʻona a me ka ammonia wai.
Noi
1) ʻO ka Potassium Iodate kahi kumu o ka iodine i hana ʻia ma ka hoʻohui ʻana i ka iodine me ka potassium hydroxide. he pauka crystalline ia i ʻoi aku ka paʻa ma mua o ka iodide. he solubility kona o 1 g i loko o 15 ml o ka wai. hoʻohana ʻia ia ma ke ʻano he mea hoʻomaikaʻi palaoa wikiwiki; hoʻohana ʻia ia me ka potassium bromate ma ke ʻano he mea oxidizing e hoʻololi i ka protein i loko o ka palaoa berena e hoʻonui ai i ka nui a me ke ʻano o ka berena. hoʻohana ʻia ia i nā mea i hoʻomoʻa ʻia.
2) He mea hoʻoheheʻe ikaika loa ka Potassium iodate i hiki ke hoʻohana ʻia i ka hoʻāʻo ʻana o kekahi mau mea lāʻau lapaʻau, no ka laʻana: benzalkonium chloride, cetrimide, hydralazine hydrochloride, potassium iodide, phenylhydrazine hydrochloride, semicarbazide hydrochloride a me nā mea like. Ma lalo o nā palena hoʻokolohua kūpono, hana ka iodate me nā iodides a me ka iodine. Eia nō naʻe, he mea hoihoi ke nānā ʻana ma ʻaneʻi e hiki ke hoʻokō pono ʻia nā titrations iodate i ke alo o nā waikawa organik saturated, ka waiʻona a me nā mea ola ʻē aʻe.
ʻO nā hana hoʻemi-ʻokikene me ka potassium iodate e pili mau ana i ka hoʻokumu ʻia ʻana o ka iodine monochloride (ICl) i loko o kahi wai o ka hopena hydrochloric acid ikaika.
3) Hiki ke hoʻohui ʻia ka Iodine i ka paʻakai ma ke ʻano o ka potassium iodide (KI) a i ʻole ka potassium iodate (KIO3). No ka mea, ʻoi aku ka paʻa o KIO3 i ke alo o nā haumia paʻakai, ka makū, a me ka ʻūpā porous, ʻo ia ke ʻano i ʻōlelo ʻia.
Hoʻemi ʻia ka potassium iodate, ka mea i hana ʻia ma ke ʻano he huahana lua, e ke kalapona i hoʻāla ʻia. Hoʻomaʻemaʻe ʻia ka huahana ma o ka crystallization mai ka wai. ʻOkoʻa, hiki ke mālama ʻia ka hao (II) iodide, i hoʻomākaukau ʻia ma ka hoʻohana ʻana i ka pauka hao a me ka iodine, me ka potassium carbonate e loaʻa ai ka potassium iodide. Hiki ke hoʻomākaukau ʻia ka potassium iodide maʻemaʻe kiʻekiʻe ma o ka hopena o ka potassium bicarbonate me ka waikawa hydriodic.
