Poov tshuaj iodide yog xim tsis muaj xim lossis dawb cubic crystal. Tsis muaj ntxhiab, nrog cov kev iab siab thiab qab ntsev. Txheeb ze ceev ceev 3.12. Melting taw tes 680 degree. Boiling point 1420 degree. Yooj yim deliquescent nyob rau hauv huab cua noo.
Cov poov tshuaj iodide yuav tsum muab cia rau hauv qhov txias, tsaus, qhuav tsev rau khoom. Lub raj mis lub qhov ncauj yuav tsum tau muab ntim. Nws yuav tsum tsis txhob khaws cia lossis thauj nrog cov tshuaj lom neeg lom. Nws yuav tsum tau tiv thaiv los ntawm nag thiab hnub ci thaum lub sijhawm thauj mus los. Ceev faj thaum thauj khoom thiab thau khoom, thiab kev co thiab kev cuam tshuam yog txwv tsis pub muaj kev puas tsuaj ntim khoom.

Siv los ntawm CAS:7681-11-0
Cov poov tshuaj Iodide feem ntau yog siv los ua kev ua kom haum rau cov hlau pickling lossis tus synosion rau lwm tus neeg mob. Poov tshuaj iodide yog cov khoom siv raw rau ua ntau yam iodides thiab dyes. Nws yog siv los ua cov duab kos duab, khoom noj khoom haus ntxiv, thiab hauv cov tshuaj uas muaj kev tiv thaiv, tshuaj rau kev tiv thaiv kev mus kawm thiab kho cov tshuaj zoo rau hyperthyroidism. Nws tseem raug siv los ua kev ntsuas cov tshuaj reagent.
Txoj Kev Ntsuam Xyuas
Iodometry: Siv cov khoom siv txo cov tshuaj pleev ntawm cov poov tshuaj iodide, nws ua rau oxidants nrog oxidants hauv ib puag ncig acidic los tsim cov iodine. Lub iodine yog ces teev nrog cov sodium dolium thiosulfate daws, thiab cov ntsiab lus ntawm cov poov tshuaj iodide raug suav nrog nws, siv hauv kev kuaj zaub mov noj.
Tus argentometry: Poov tshuaj iodide reacts nrog nyiaj nitrate los ua cov nyiaj iodide nag lossis daus. Titrate nrog cov txheej txheem nyiaj nitrate uas muaj poov tshuaj chromate raws li qhov ntsuas. Thaum cib-liab nyiajromate precipitive tshwm, nws qhia txog qhov kawg taw tes ntawm lub kaum tes, thiab cov ntsiab lus ntawm cov poov tshuaj Iodide tuaj yeem suav tau. Thaum txiav txim siab tas li ntawm poov tshuaj Iodide, cuam tshuam los ntawm cov lus hauv hats yuav tsum tau cais tawm.
