Potassium iodate bụ nnu jupụtara na iodine nwere usoro KIO3. N'ebe okpomọkụ na iru mmiri, a na-eme ka uzuoku iodine dị na hydrolyze n'ihi na potassium iodide dị na hygroscopicity. Ma e jiri ya tụnyere potassium iodide, potassium iodate kwụsiri ike ma nwee ndụ ogologo oge. Ọ bụ ihe na-egbochi ike nke redioaktivu iodine site na gland thyroid.
Njirimara Ngwaahịa
Potassium iodate bụ kristal monoclinic ma ọ bụ ntụ ọcha kristal na-enweghị agba. Enweghị isi. A na-agbaze na mmiri, a na-agwakọta acid, ethylenediamine, ethanolamine, na potassium iodide mmiri; a na-agbaze ntakịrị na mmiri sulfur dioxide; a naghị agbaze na alcohols na ammonia.
Kristal na-enweghị agba ma ọ bụ ntụ ọcha; nhazi monoclinic; njupụta 3.90 g/cm3; kwụsiri ike na okpomọkụ nkịtị; na-agbaze na 560°C na nkewa akụkụ, na-ewepụta oxygen; na-agbaze nke ọma na mmiri oyi; 4.74 g/100mL na 0°C; na-agbaze nke ọma na mmiri esi 32.3 g/100mL na 100°C; na-agbaze na ngwọta potassium iodide; anaghị agbaze na mmanya na amonia mmiri mmiri.

1) Potassium Iodate bụ isi iyi nke iodine nke e ji potassium hydroxide mee. Ọ bụ ntụ kristal nke kwụsiri ike karịa iodide. Ọ nwere ike ịgbaze 1 g na mmiri 15 ml. A na-eji ya eme ka mgwakota agwa dị ngwa ngwa; a na-eji ya na potassium bromate dị ka ihe na-eme ka oxidizing gbanwee protein dị na ntụ ọka achịcha nke na-akwalite olu na ọdịdị achịcha. A na-eji ya eme ihe na ihe e ji eme achịcha.
2) Potassium iodate bụ ihe na-eme ka oxidation sie ike nke enwere ike iji na nnwale nke ọtụtụ ihe ọgwụ, dịka ọmụmaatụ: benzalkonium chloride, cetrimide, hydralazine hydrochloride, potassium iodide, phenylhydrazine hydrochloride, semicarbazide hydrochloride na ihe ndị yiri ya. N'okpuru paramita nnwale kwesịrị ekwesị, iodate na-emeghachi omume n'ọtụtụ na iodides na iodine. Agbanyeghị, ọ dị mma ịhụ ebe a na enwere ike ime titrations nke iodate nke ọma n'ihu acid organic juru eju, mmanya na ọtụtụ ihe ndị ọzọ dị ndụ.
Usoro mbelata oxidation na potassium iodate na-adaberekarị na nhazi nke iodine monochloride (ICl) n'ime ihe ngwọta hydrochloric acid siri ike.
3) Enwere ike itinye Iodine na nnu n'ụdị potassium iodide (KI) ma ọ bụ potassium iodate (KIO3). Ebe ọ bụ na KIO3 nwere nkwụsi ike dị elu n'ihu ihe na-adịghị ọcha nnu, iru mmiri, na ngwugwu oghere, ọ bụ ụdị akwadoro.
A na-ebelata potassium iodate, nke a na-emepụta dị ka ngwaahịa nke abụọ, site na carbon a na-arụ ọrụ. A na-eme ka ngwaahịa ahụ dị ọcha site na kristal site na mmiri. Ma ọ bụghị ya, a pụrụ iji potassium carbonate gwọọ iron (II) iodide, nke e ji ntụ ígwè na iodine kwadebe, iji nweta potassium iodide. Enwere ike ịkwadebe potassium iodide dị ọcha site na mmeghachi omume nke potassium bicarbonate na hydriodic acid.
