Qhov sib txawv tseem ceeb ntawm sodium hypochlorite thiab hydrogen peroxide yog tias sodium hypochlorite tuaj yeem tso cov roj chlorine, hos hydrogen peroxide tsis tuaj yeem tso cov roj chlorine.
Sodium hypochlorite yog ib qho inorganic ionic compound uas muaj sodium thiab hypochlorite ions, thaum hydrogen peroxide yog ib qho inorganic compound uas muaj cov tshuaj formula H2O2 . Ob qho tib si sodium hypochlorite thiab hydrogen peroxide yog cov oxidizing muaj zog.
Sodium Hypochlorite yog dab tsi?
Sodium hypochlorite yog ib qho inorganic ionic compound uas muaj sodium thiab hypochlorite ions. Nws yog sodium ntsev ntawm hypochlorous acid. Cov tshuaj no muaj cov tshuaj formula NaOCl. Nws qhov hnyav yog 74.44 g / mol. Feem ntau, sodium hypochlorite tsis ruaj khov thiab tej zaum yuav zoo li decompose explosively. Txawm li cas los xij, nws daim ntawv pentahydrate ruaj khov. Ntxiv mus, nws daim ntawv hydrated muaj xim daj-ntsuab-daj thiab tshwm sim raws li cov khoom. Txawm hais tias daim ntawv hydrated no ruaj khov dua li daim ntawv anhydrous, peb yuav tsum tau tso rau hauv tub yees kom nws ruaj khov. Ntxiv mus, sodium hypochlorite muaj qab zib, zoo li chlorine tsw.
Muaj ob peb txoj hauv kev npaj rau qhov sib xyaw no. Peb tuaj yeem yooj yim npaj sodium hypochlorite los ntawm cov tshuaj tiv thaiv ntawm ntsev (NaCl) thiab ozone. Nws yog ib txoj kev yooj yim tab sis haum rau kev tshawb fawb lub hom phiaj. Rau kev xav tau kev lag luam, qhov sib xyaw no yog tsim los ntawm cov txheej txheem Hooker. Hauv cov txheej txheem no, cov roj chlorine tau dhau los ntawm dilute sodium hydroxide tov, uas muab sodium hypochlorite thiab sodium chloride.
Y Hydrogen Peroxide yog dab tsi?
Hydrogen peroxide yog ib qho inorganic compound uas muaj cov tshuaj formula H2O2 Daim ntawv ntshiab ntawm hydrogen peroxide muaj xim daj ntseg., thiab nws tshwm sim raws li cov kua ntshiab. Cov kua no me ntsis viscos dua li dej. Qhov tseeb, nws yog qhov yooj yim tshaj plaws peroxide ntawm tag nrho cov tshuaj peroxide.
Muaj qee qhov kev siv tseem ceeb ntawm hydrogen peroxide; ntawm lawv, cov ntawv thov loj suav nrog siv nws ua oxidizer, tshuaj dawb, thiab tshuaj tua kab mob. Muaj ib qho tsis ruaj khov peroxide ntawm ob lub atoms ntawm cov pa oxygen hauv qhov sib xyaw no; Yog li, lub compound yog heev reactive. Yog li ntawd, nws maj mam decomposes thaum raug rau lub teeb. Tsis tas li ntawd, peb yuav tsum khaws cov tshuaj no nrog lub stabilizer hauv cov kua qaub tsis muaj zog.
Cov molar loj ntawm hydrogen peroxide yog 34.014 g / mol. Hydrogen peroxide muaj ntxhiab tsw me ntsis. Nws cov ntsiab lus melting yog -0.43 ° C, thiab nws qhov kub ntawm 150.2 ° C. Txawm li cas los xij, yog tias peb boil hydrogen peroxide rau qhov kub no, nws xyaum ua kom tawg thermal decomposition. Tsis tas li ntawd, qhov sib xyaw no yog miscible nrog dej vim nws tuaj yeem tsim hydrogen bonds. Nws tsim ib qho eutectic sib tov nrog dej (ib homogenous sib tov uas melts lossis solidifies ntawm ib qho kub). Qhov kev sib xyaw no qhia txog kev nyuaj siab khov kho.
Qhov txawv ntawm Sodium Hypochlorite thiab Hydrogen Peroxide yog dab tsi?
Qhov sib txawv tseem ceeb ntawm sodium hypochlorite thiab hydrogen peroxide yog tias sodium hypochlorite tuaj yeem tso cov roj chlorine, hos hydrogen peroxide tsis tuaj yeem tso cov roj chlorine. Ntxiv mus, cov nyhuv oxidative ntawm sodium hypochlorite yog qhov sib piv siab dua li ntawm hydrogen peroxide. Hydrogen peroxide muaj txiaj ntsig zoo li tshuaj tua kab mob me me rau ntawm daim tawv nqaij los tiv thaiv kev kis mob me me, khawb, kub hnyiab, thiab lwm yam., whereas sodium hypochlorite muaj txiaj ntsig zoo rau kev ntxuav dej, ntawv ntxuav, khaws zaub mov, txheej txheem kho mob, thiab lwm yam.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm sodium hypochlorite thiab hydrogen peroxide.
Summary – Sodium Hypochlorite vs Hydrogen Peroxide
Sodium hypochlorite thiab hydrogen peroxide yog ib qho tseem ceeb hauv cov tebchaw uas muaj peev xwm ua tau zoo oxidizing cov neeg ua haujlwm. Qhov sib txawv tseem ceeb ntawm sodium hypochlorite thiab hydrogen peroxide yog tias sodium hypochlorite tuaj yeem tso cov roj chlorine, hos hydrogen peroxide tsis tuaj yeem tso cov roj chlorine. Thaum sodium hypochlorite qhia tau hais tias muaj zog bleaching thiab ntxuav cov nyhuv, hydrogen peroxide qhia tau hais tias tsis tshua muaj oxidation nyhuv.
