Qhov Tseem Ceeb Qhov txawv - Sodium Chlorite vs Sodium Hypochlorite
Sodium chlorite thiab sodium hypochlorite yog cov ntsev ntsev siv hauv kev lag luam. Ob lub tebchaw no tseem ceeb heev li cov tshuaj bleaching thiab tshuaj tua kab mob. Tab sis lawv txawv heev ntawm ib leeg thaum lawv cov khoom siv tshuaj xws li molar mass thiab lub cev lub cev raug txiav txim siab. Sodium chlorite feem ntau yog siv hauv kev tsim cov ntawv thiab ua cov tshuaj tua kab mob. Sodium hypochlorite yog siv los ua tshuaj tua kab mob los ntawm dissolving hauv dej los ua "kua tshuaj dawb". Qhov sib txawv tseem ceeb ntawm sodium chlorite thiab sodium hypochlorite yog tias sodium chlorite muaj chlorine atoms muaj +3 oxidation lub xeev thaum sodium hypochlorite muaj chlorine atoms muaj +1 oxidation xeev.
Sodium Chlorite yog dab tsi?
Sodium chlorite yog ib qho tshuaj inorganic compound uas muaj cov tshuaj formula NaClO2 Cov molar mass ntawm no compound yog 90.438 g / mol thaum nws yog anhydrous. Muaj ib daim ntawv hydrate ib yam nkaus (muaj peb lub molecules dej txuam nrog sodium chlorite molecule uas nws molar loj yog 144.48 g / mol). Cov tshuaj tseem hu ua chlorous acid. Nws yog ib qho ionic compound uas muaj sodium cation (Na+) thiab chlorite anion (ClO2–).

Nws muaj raws li cov hmoov dawb crystalline uas tsis muaj ntxhiab tsw. Kev kub hnyiab ntawm sodium chlorite yog qhov nyuaj, tab sis nws tuaj yeem ua kom kub hnyiab ntawm cov organic tebchaw. Yog li, sodium chlorite tuaj yeem siv los ua cov khoom tawg nrog cov khoom siv hluav taws xob. Sodium chlorite decomposes ntawm li 180-200◦C.
Sodium chlorite yog soluble tsawg hauv dej tab sis ntau soluble hauv methanol thiab ethanol. Cov qauv siv lead ua ntawm cov compound yog monoclinic. Sodium chlorite feem ntau yog siv rau hauv kev tsim cov ntawv thiab kuj yog tshuaj tua kab mob. Nws yog ib qho zoo oxidizing tus neeg sawv cev; yog li no yog siv los ntxuav ntau yam ntaub ntawv xws li ntoo, roj, thiab lwm yam.
Cov tshuaj dawb chlorous acid (HClO 2) tsis ruaj khov thiab nws tsis muaj qhov tseem ceeb hauv kev lag luam. Tab sis sodium ntsev ntawm cov kua qaub no ruaj khov thiab tseem pheej yig. Feem ntau ntawm cov sij hawm, sodium chlorite yog muab los ntawm sodium chlorate, uas muaj cov tshuaj formula NaClO3 Cov txheej txheem tsim khoom yog ib txoj hauv kev ncaj qha uas chlorine dioxide (ClO 2) yog tsim thaum xub thawj. Chlorine dioxide yog tawg heev thiab nws yog tsim los ntawm kev txo sodium chlorate nyob rau hauv ib tug muaj zog acid nyob rau hauv lub xub ntiag ntawm ib tug txo tus neeg saib xyuas zoo li sodium sulfite. Tom qab ntawd cov tshuaj chlorine dioxide yog absorbed rau hauv cov tshuaj alkaline nrog rau txo los ntawm hydrogen peroxide (H2O2). Qhov no yields sodium chlorite.
Sodium Hypochlorite yog dab tsi?
Sodium hypochlorite yog ib qho inorganic compound uas muaj cov tshuaj formula NaClO. Qhov sib piv atomic ntawm sodium, chlorine thiab oxygen yog 1: 1: 1. Lub compound yog tsim los ntawm sodium cation khi rau hypochlorite anion. Yog li nws yog sodium ntsev ntawm hypochlorous acid. Thaum sodium hypochlorite yaj nyob rau hauv dej, nws yog hu ua kua bleach vim nws bleaching zog.

Cov molar loj ntawm sodium hypochlorite yog 74.44 g / mol. Cov tsos ntawm no compound yuav piav raws li ib tug greenish yellowish khoom. Nws kuj muaj ntxhiab tsw qab. Lub melting point ntawm sodium hypochlorite yog 18 ° C thiab boiling point yog 101 ◦C.
Sodium hypochlorite feem ntau yog siv los ua tshuaj tua kab mob thiab ua cov tshuaj bleaching. Yuav luag tag nrho cov kua tshuaj dawb uas peb siv hauv tsev muaj nyob ib ncig ntawm 3-8% ntawm sodium hypochlorite. Cov tshuaj no muaj cov khoom de-staining; Yog li nws yog siv los tshem tawm cov pwm stains, kho hniav stains, thiab lwm yam. Sodium hypochlorite yog cov tshuaj tua kab mob zoo vim nws muaj ntau yam kev tiv thaiv kab mob.
Kev tsim cov sodium hypochlorite yog ua tiav ntawm Hooker txheej txheem. Nws yog ib tug loj-scale, industrial txoj kev. Ntawm no, sodium hypochlorite yog tsim los ntawm kev dhau cov roj chlorine rau hauv qhov txias, dilute sodium hydroxide tov. Lwm yam khoom uas tau muab los ntawm txoj kev no yog sodium chloride (NaCl).
Dab tsi yog qhov zoo sib xws ntawm Sodium Chlorite thiab Sodium Hypochlorite?
- Sodium Chlorite thiab Sodium Hypochlorite yog tsim los ntawm Na, Cl thiab O atoms.
- ob leeg yog tshuaj tua kab mob zoo.
Qhov txawv ntawm Sodium Chlorite thiab Sodium Hypochlorite yog dab tsi?
