Iodometry, hu ua iodometric titration, yog txheej txheem ntawm kev tshuaj ntsuam xyuas tshuaj volumetric, redox titration qhov twg qhov tsos lossis ploj ntawm theem pib iodine qhia qhov kawg. … Hauv ib qho iodometric titration, cov hmoov txhuv nplej siab yog siv los ua qhov taw qhia vim nws tuaj yeem nqus cov I2 uas tau tso tawm.
Yuav ua li cas yog txheej txheem ntawm iodometric titration?
Ntxiv rau Erlenmeyer lub hwj 50 mL ntawm cov dej demineralized, 10 mL ntawm sulfuric acid tov, 10-15 mLs ntawm poov tshuaj iodide tov, thiab ob tee ammonium molybdate tov. Titrate nrog 0.1 N sodium thiosulfate kom faint daj lossis straw xim. Swirl los yog do maj mam thaum lub sij hawm titration kom txo qis iodine poob.
Iodometric txoj hauv kev yog dab tsi?
Lub hauv paus ntsiab lus yog iodine yog liberated los ntawm kev ntxiv sulfuric acid rau kev daws ntawm iodised ntsevPotassium iodide tov yog ntxiv kom cov iodine nyob rau hauv lub xeev yaj. Iodine liberated yog titrated nrog sodium thiosulphate tov los tsim sodium iodide thiab sodium tetrathionate.
Vim li cas iodometric titration ua tiav sai heev?
Nyob rau hauv cov ntaub ntawv no, titration ntawm liberated iodine yuav tsum tau ua kom tiav sai sai thiaj li yuav tshem tawm tsis raug rau cov huab cua txij li thaum ib tug kua qaub nruab nrab yog ib qho zoo rau atmospheric oxidation ntawm tshaj iodide ion.
Vim li cas peb siv iodine hauv iodometric titration?
Iodometry yog siv txhawm rau txiav txim siab cov tshuaj oxidising los ntawm cov txheej txheem tsis ncaj uas cuam tshuam nrog iodine ua tus intermediary. Nyob rau hauv lub xub ntiag ntawm iodine, thiosulphate ions oxidise quantitatively rau tetrathionate ions.
