Qhov sib txawv tseem ceeb ntawm sodium sulphate thiab sodium sulphite yog tias sodium sulphate muaj sulphate anion uas muaj ib tus sulfur atom thiab plaub oxygen atoms whereas sodium sulphite muaj ib tug sulfite anion uas muaj ib tug sulfur atom thiab peb oxygen atoms. Ntxiv mus, sodium sulphate yog hygroscopic thaum sodium sulphite tsawg soluble hauv dej piv.
Ob qho tib si sodium sulphate thiab sodium sulphite yog cov tshuaj inorganic. Thaum xav txog cov qauv tshuaj ntawm ob lub tebchaw no, lawv sib txawv ntawm ib leeg ntawm cov pa oxygen atoms uas lawv muaj.
Sodium Sulphate yog dab tsi?
Sodium sulphate yog ib qho inorganic compound uas muaj cov tshuaj formula Na2SO4 Nws muaj ob peb daim ntawv hydrated ib yam nkaus. Feem ntau cov hydrate yog decahydrate daim ntawv. Tag nrho cov ntaub ntawv anhydrous thiab hydrated yog dawb crystalline solids. Ntxiv mus, qhov sib xyaw no yog hygroscopic.
Daim duab 01: Sodium Sulphate
Cov molar loj ntawm cov tshuaj no yog 142.04 g / mol (anhydrous daim ntawv). Nws tsis muaj ntxhiab, thiab cov ntsiab lus melting thiab boiling yog 884 ° C thiab 1, 429 ° C. Yog li ntawd, nws yuav muaj xws li orthorhombic lossis hexagonal siv lead ua. Qhov tseem ceeb tshaj, qhov sib xyaw no ruaj khov heev. Nws yog li no unreactive rau ntau oxidizing thiab txo tus neeg sawv cev. Txawm li cas los xij, ntawm qhov kub siab, nws hloov mus rau hauv sodium sulphide ntawm carbothermal txo.
Tsis tas li ntawd, qhov sib xyaw no yog cov ntsev nruab nrab. Yog li ntawd, cov tshuaj aqueous ntawm cov tshuaj no muaj pH ntawm 7. Tsis tas li ntawd, cov tshuaj no tuaj yeem cuam tshuam nrog sulfuric acid muab cov kua qaub ntsev sodium bisulfate. Thaum xav txog cov ntawv thov ntawm cov khoom sib xyaw no, daim ntawv decahydrate yog qhov tseem ceeb hauv kev tsim cov tshuaj detergents thiab ntau lwm yam khoom. Ntxiv mus, nws yog ib qho tseem ceeb hauv Kraft txheej txheem thiab ntawv pulping.
Sodium Sulphite yog dab tsi?
Sodium sulphite yog ib qho inorganic compound uas muaj cov tshuaj formula Na2SO3 Nws yog ib qho ntsev ntawm sulfurous acid. Nws tsim raws li cov khoom ntawm sulfur dioxide txhuam hauv cov txheej txheem roj-gas desulfurization. Ntxiv mus, nws yog ib qho tseem ceeb raws li ib tug preservative nyob rau hauv khaws cia qhuav txiv hmab txiv ntoo (kom khaws cov xim).
Daim duab 02: Ib daim ntawv Anhydrous ntawm Sodium Sulphite
Cov molar loj yog 126.04 g / mol. Lub melting point yog 33.4 ° C, thiab nyob rau ntawm qhov kub thiab txias, nws decomposes; yog li ntawd, tsis muaj qhov kub siab rau qhov no. Tsis tas li ntawd, qhov sib xyaw no tuaj yeem tsim bisulfite adduct los ntawm cov tshuaj tiv thaiv nrog aldehydes, ketones, uas tsim sulfonic acid. Nws muaj txiaj ntsig zoo hauv kev ua kom huv aldehydes lossis ketones. Ntxiv rau qhov ntawd, qhov sib xyaw no tsis ruaj khov; Nws tuaj yeem decomposed txawm tias tsis muaj zog acids. Thiab, qhov decomposition no tsim cov roj sulfur dioxide. Qhov pH ib txwm muaj ntawm cov kua dej saturated yog 9. Txawm li cas los xij, thaum nws raug huab cua, nws thiaj li hloov mus ua sodium sulphate.
Qhov txawv ntawm Sodium Sulphate thiab Sodium Sulphite yog dab tsi?
Qhov sib txawv tseem ceeb ntawm sodium sulphate thiab sodium sulphite yog lawv cov qauv molecular. Tsis tas li, muaj lwm qhov sib txawv ntawm sodium sulphate thiab sodium sulphite hauv lawv cov khoom siv tshuaj thiab lub cev xws li stability, solubility, boiling thiab melting point, thiab lwm yam.
Cov ntawv qhia hauv qab no nthuav tawm cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm sodium sulphate thiab sodium sulphite hauv daim ntawv tabular.
Summary – Sodium Sulphate vs Sodium Sulphite
Sodium sulphate thiab sodium sulphite yog inorganic ntsev ntawm sodium. Qhov sib txawv tseem ceeb ntawm sodium sulphate thiab sodium sulphite yog tias sodium sulphate muaj sulphate anion, uas muaj ib tug sulfur atom thiab plaub oxygen atoms whereas sodium sulphite muaj ib tug sulfite anion, uas muaj ib tug sulfur atom thiab peb oxygen atoms.
