Qhov sib txawv tseem ceeb ntawm sodium periodate thiab sodium metaperiodate yog sodium periodate yog ib qho hypovalent compound, whereas sodium metaperiodate yog ib qho hypervalent compound.
Sodium periodate yog ib qho inorganic compound uas muaj cov tshuaj formula NaIO4. Nws yog ib qho hypovalent compound, uas txhais tau hais tias nws muaj lub hauv paus atom uas muaj tsawg tshaj li yim electrons nyob rau hauv lub valence electron plhaub. Sodium metaperiodate yog ib qho tshuaj inorganic tshuaj lom neeg, thiab nws yog ib qho derivative ntawm sodium periodate. Nws yog ib tug hypervalent molecule, uas txhais tau hais tias nws muaj ib los yog ntau lub ntsiab pab pawg neeg muaj ntau tshaj yim electrons nyob rau hauv nws valence shells.
Sodium Periodate yog dab tsi?
Sodium periodate yog ib qho inorganic compound uas muaj cov tshuaj formula NaIO4. Nws yog ib qho ntsev inorganic uas muaj sodium cation thiab periodate anion. Peb tuaj yeem hu nws tias sodium ntsev ntawm periodic acid. Zoo ib yam li ntau lwm yam periodates, cov tshuaj no kuj muaj nyob rau hauv ntau hom, xws li sodium metaperiodate form thiab sodium orthoperiodate form. Ob hom no yog cov muaj txiaj ntsig oxidizing agents.
Daim duab 01: Cov Qauv Tshuaj ntawm Sodium Periodate
Sodium periodate tshwm li cov muaju dawb uas yog soluble hauv dej. Cov tshuaj no kuj yog soluble hauv acids. Feem ntau, cov khoom no yog npaj rau hauv daim ntawv ntawm sodium hydrogen periodate uas yog muag. Ntxiv mus, peb tuaj yeem tsim sodium periodate los ntawm oxidation ntawm iodates nrog chlorine thiab sodium hydroxide los yog los ntawm iodides los ntawm oxidation nrog bromine thiab sodium hydroxide. Txawm li cas los xij, niaj hnub kev npaj muaj xws li electrochemical oxidation ntawm iodates ntawm PbO2 anode.
Sodium Metaperiodate yog dab tsi?
Sodium metaperiodate yog ib qho tshuaj inorganic compound, thiab nws yog ib qho derivative ntawm sodium periodate. Nws yog ib qho tseem ceeb raws li lub hauv paus ntawm periodic acid, ib tug analytical agent, thiab oxidizing tus neeg sawv cev, uas yog koom nyob rau hauv lub oxidation ntawm cellulose. Tsis tas li ntawd, cov tshuaj no koom nrog hauv kev sib cais ntawm vicinal diols los npaj ob aldehydes.
Daim duab 02: Cov Qauv Tshuaj ntawm Metaperiodate Anion
Cov tshuaj no feem ntau tshwm sim hauv daim ntawv sodium metaperiodate trihydrate. Daim ntawv ntawm sodium periodate no feem ntau yog npaj los ntawm lub cev qhuav dej ntawm sodium hydrogen periodate nrog nitric acid. Tsis tas li ntawd, peb tuaj yeem ua qhov ntawd los ntawm lub cev qhuav dej orthoperiodic acid siv kev kho cua sov rau cov tshuaj tiv thaiv sib tov rau 100 degrees Celsius nyob rau hauv lub tshuab nqus tsev.
Qhov txawv ntawm Sodium Periodate thiab Sodium Metaperiodate yog dab tsi?
Sodium periodate thiab sodium metaperiodate yog inorganic sodium ntsev tebchaw. Sodium periodate yog ib qho inorganic compound uas muaj cov tshuaj formula NaIO4. Sodium metaperiodate yog ib qho tshuaj inorganic compound, thiab nws yog ib qho derivative ntawm sodium periodate. Qhov sib txawv tseem ceeb ntawm sodium periodate thiab sodium metaperiodate yog tias sodium periodate yog ib qho hypovalent compound, whereas sodium metaperiodate yog ib qho hypervalent compound. Ntxiv mus, peb tuaj yeem npaj sodium periodate los ntawm oxidation ntawm iodates nrog chlorine thiab sodium hydroxide los yog los ntawm iodides los ntawm oxidation nrog bromine thiab sodium hydroxide. Ntawm qhov tod tes, peb npaj sodium metaperiodate los ntawm lub cev qhuav dej ntawm sodium hydrogen periodate nrog nitric acid.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm sodium periodate thiab sodium metaperiodate nyob rau hauv daim ntawv tabular rau ib sab sib piv.
Summary – Sodium Periodate vs Sodium Metaperiodate
