Qhov sib txawv tseem ceeb ntawm sodium nitrate thiab sodium nitrite yog tias sodium nitrate zoo li tsis muaj xim muaju thaum sodium nitrite zoo li yellowish crystals.
Ob qho tib si sodium nitrate thiab sodium nitrite yog ionic compounds ntawm sodium, nitrogen thiab oxygen tshuaj lom neeg. Ob lub tebchaw no txawv ntawm ib leeg raws li cov anion tam sim no nrog rau sodium cation.
Nitrate yog dab tsi?
Sodium nitrate yog ib qho inorganic compound uas muaj cov tshuaj formula NaNO3 Nws tshwm li cov xim dawb-colourless crystalline khoom. Nws yog alkali hlau nitrate ntsev, uas yog lub npe hu ua Chile s altpetre hauv mineralogy. Cov tshuaj no yog dej-soluble heev. Tom qab dissolution, nws tsim sodium cations thiab nitrate anions. Yog li ntawd, nws yog ib qho tseem ceeb raws li ib qho yooj yim nitrate muaj nyob rau hauv sib txawv synthesis txheej txheem, chiv ntau lawm, thiab lwm yam.
Daim duab 01: Sodium Nitrate
Cov molar loj ntawm sodium nitrate yog 84.9 g / mol. Nws muaj ntxhiab tsw qab. Ntxiv nrog rau kev khawb av los ntawm kev tso nyiaj, peb tuaj yeem tsim cov sodium nitrate hauv chav kuaj thiab. Nyob ntawd, peb tuaj yeem neutralize nitric acid nrog sodium carbonate lossis sodium bicarbonate. Nws kuj tseem tuaj yeem ua qhov nruab nrab no siv sodium hydroxide. Cov qauv siv lead ua ntawm qhov tsim sodium nitrate tuaj yeem txhais tau tias yog cov qauv siv lead ua trigonal, tab sis qee zaum nws muab cov qauv siv lead ua rhombohedral.
Nitrite yog dab tsi?
Sodium nitrite yog ib qho inorganic compound uas muaj cov tshuaj formula NaNO2 Nws muaj xim dawb-daj crystalline tsos. Qhov no compound yog heev dej-soluble thiab hygroscopic ib yam nkaus. Cov molar mass ntawm no compound 68.9 g / mol. Ntxiv mus, cov qauv siv lead ua ntawm sodium nitrite yog orthorhombic. Kev tsim khoom ntawm sodium nitrite tuaj yeem ua tau ob txoj hauv kev: txo cov ntsev nitrate lossis oxidation ntawm qis nitrogen oxides.
Daim duab 02: Sodium nitrite
Kev siv loj ntawm sodium nitrite hauv kev lag luam yog tsim cov organonitrogen tebchaw. Nyob ntawd, peb tuaj yeem siv nws ua ib qho reagent rau kev hloov pauv ntawm amines rau hauv diazo tebchaw. Cov diazo tebchaw no yog tus yuam sij rau ntau azo tebchaw xws li dyes. Tsis tas li ntawd, sodium nitrite yog cov tshuaj muaj txiaj ntsig zoo hauv kev ua xua cyanide. Nws kuj yog ib qho tseem ceeb ntawm cov khoom noj ntxiv vim tias qhov sib ntxiv ntawm sodium nitrite yog ib qho yooj yim uas muab cov nqaij ua tiav ib qho xim liab dawb. Cov saj ntawm cov nqaij kuj tseem txhim kho los ntawm qhov sib xyaw no. Txawm li cas los xij, sodium nitrite tau lees paub tias yog tshuaj lom me ntsis.
Qhov txawv ntawm Sodium Nitrate thiab Sodium Nitrite yog dab tsi?
Ob qho tib si sodium nitrate thiab sodium nitrite yog ionic compounds ntawm sodium, nitrogen thiab oxygen tshuaj lom neeg. Qhov sib txawv tseem ceeb ntawm sodium nitrate thiab sodium nitrite yog tias sodium nitrate zoo li tsis muaj xim muaju thaum sodium nitrite zoo li yellowish crystals. Cov anion hauv sodium nitrate tsis yog NO3 - thiab hauv sodium nitrite nws tsis yog NO2– Ob lub tebchaw no yog dej-soluble tab sis sodium nitrite yog hygroscopic ib yam nkaus.
Ntxiv mus, cov qauv siv lead ua ntawm sodium nitrate yog trigonal thaum cov qauv siv lead ua ntawm sodium nitrite yog orthorhombic. Peb tuaj yeem tsim sodium nitrate ntawm neutralizing nitric acid nrog sodium carbonate lossis sodium bicarbonate. Peb tuaj yeem tsim sodium nitrite hauv ib qho ntawm ob txoj hauv kev: txo cov ntsev nitrate lossis oxidation ntawm qis nitrogen oxides.
Hauv qab infographic qhia txog qhov sib txawv ntawm sodium nitrate thiab sodium nitrite.
Summary – Sodium Nitrate vs Sodium Nitrate
Ob qho tib si sodium nitrate thiab sodium nitrite yog ionic compounds ntawm sodium, nitrogen thiab oxygen tshuaj lom neeg. Qhov sib txawv tseem ceeb ntawm sodium nitrate thiab sodium nitrite yog tias sodium nitrate zoo li tsis muaj xim muaju thaum sodium nitrite zoo li yellowish crystals.
