Qhov sib txawv tseem ceeb ntawm sodium chloride thiab sodium nitrate yog sodium chloride yog kev sib xyaw ntawm sodium cation thiab chloride anion whereas sodium nitrate yog kev sib xyaw ntawm sodium cation thiab nitrate anion.
Ob qho tib si sodium chloride thiab sodium nitrate yog ionic compounds. Lawv muaj ib tug cation thiab anion ua ke los ntawm ib tug ionic daim ntawv cog lus. Lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv vim tias lawv muaj cov anions sib txawv ua ke nrog cov cations zoo sib xws (sodium cations).
Sodium Chloride yog dab tsi?
Sodium chloride yog ib qho inorganic compound ua los ntawm sodium cation thiab chloride anion. Cov tshuaj formula ntawm no compound yog NaCl. Feem ntau, nws yog "nqaij" txij li cov ntsev uas peb noj ua cov khoom noj ntxiv feem ntau muaj sodium chloride nrog rau qee cov kab sib txuas xws li magnesium chloride.
Sodium chloride yog ib qho ionic compound. Nws muaj 1: 1 sodium ions thiab chloride ions. Sodium chloride yog qhov sib xyaw ua ke uas yog lub luag haujlwm rau tus yam ntxwv saj hauv dej hiav txwv. Cov mis hnyav ntawm sodium chloride yog 58.44 g / mol. Sodium chloride yog dawb thaum nws ntshiab. Nws zoo nkaus li pob tshab lossis translucent cubic crystals. Lub melting point ntawm sodium chloride yog 801oC, thaum lub boiling point yog 1465oC. Nws yog zoo soluble nyob rau hauv dej. Nyob rau hauv cov qauv siv lead ua ntawm sodium chloride, txhua ion yog ib puag ncig los ntawm rau ions ntawm tus nqi sib txawv. Cov ions no nyob hauv cov qauv octahedron tsis tu ncua.
Daim duab 01: Kev sib cais ntawm Sodium Chloride hauv dej
Sodium chloride yog hygroscopic. Qhov ntawd txhais tau tias, nws tuaj yeem nqus dej vapor los ntawm huab cua thaum raug rau qhov chaw. Tsis tas li ntawd, qhov sib xyaw no yog qhov tseem ceeb rau peb kom tswj tau qhov sib npaug ntawm electrolytic hauv peb lub cev. Nws kuj tseem siv los khaws qee yam khoom noj.
Nitrate yog dab tsi?
Sodium nitrate yog ib qho inorganic compound uas muaj sodium cation thiab nitrate anion. Nws muaj cov tshuaj formula NaNO3 Nws zoo nkaus li 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 02: Cov Crystals ntawm 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 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.
Qhov txawv ntawm Sodium Chloride thiab Sodium Nitrate yog dab tsi?
Qhov sib txawv tseem ceeb ntawm sodium chloride thiab sodium nitrate yog sodium chloride yog kev sib xyaw ntawm sodium cation thiab chloride anion, whereas sodium nitrate yog kev sib xyaw ntawm sodium cation thiab nitrate anion. Cov tshuaj formula ntawm sodium chloride yog NaCl thaum cov tshuaj formula ntawm sodium nitrate yog NaNO3
Cov duab hauv qab no qhia txog qhov sib txawv ntawm sodium chloride thiab sodium nitrate.
Summary – Sodium Chloride vs Sodium Nitrate
Sodium chloride thiab sodium nitrate yog ionic compounds. Qhov sib txawv tseem ceeb ntawm sodium chloride thiab sodium nitrate yog tias sodium chloride yog kev sib xyaw ntawm sodium cation thiab chloride anion whereas sodium nitrate yog kev sib xyaw ntawm sodium cation thiab nitrate anion.
