Qhov sib txawv tseem ceeb ntawm ammonium hydroxide thiab sodium hydroxide yog tias ammonium hydroxide tshwm sim hauv cov kua hauv lub xeev thaum sodium hydroxide tshwm sim hauv lub xeev khov ntawm chav sov.
Txawm hais tias ammonium hydroxide thiab sodium hydroxide yog -OH muaj ionic compounds, lawv muaj cov tshuaj sib txawv thiab lub cev. Kab lus no saib qhov sib txawv ntawm ammonium hydroxide thiab sodium hydroxide.
Ammonium Hydroxide yog dab tsi?
Ammonium hydroxide yog cov kua uas muaj cov tshuaj formula NH4OH. Nws kuj yog ib qho inorganic compound. Peb hu nws cov tshuaj ammonia vim tias qhov sib xyaw no tsim thaum ammonia gas reacts nrog dej. Yog li ntawd, peb tuaj yeem txhais tau tias NH3(aq). Txawm hais tias lub npe ammonium hydroxide implies lub hav zoov ntawm ib tug alkaline compound, nws yog tsis yooj yim sua kom cais cov tshuaj compound ammonium hydroxide.
Daim duab 01: Ammonia daws
Cov molar loj ntawm cov tshuaj no yog 35.04 g / mol, thiab nws zoo li cov kua tsis muaj xim. Cov kua no muaj ntxhiab tsw ntxhiab heev, thiab nws qhov kub ntawm qhov kub yog -57.5 ° C thaum lub boiling point yog 37.7 ° C. Nws yog siv los ua lub tsev ntxhua khaub ncaws, ua ib qho alkyl amine precursor, rau kev kho dej, thiab ntau lwm yam kev siv.
Dab tsi yog Sodium Hydroxide
Sodium hydroxide yog hlau hydroxide nrog cov tshuaj formula NaOH. Cov neeg feem coob paub cov tshuaj no ua caustic soda. Sodium hydroxide yog ib qho ionic compound ua los ntawm sodium cations (Na +) thiab hydroxide (OH–) anions. Nws yog lub hauv paus muaj zog.

Cov molar loj ntawm sodium hydroxide yog 39.99 g / mol. Sodium hydroxide yog ib qho khoom nyob rau hauv chav tsev kub thiab tshwm li dawb, waxy crystals uas yog opaque. Nws tsis muaj ntxhiab tsw. Lub melting point ntawm sodium hydroxide yog 318 ° C, thaum lub boiling point yog 1,388 ° C.
Vim tias sodium hydroxide yog ib qho tseem ceeb heev, nws tuaj yeem ua rau kub hnyiab heev. Tsis tas li ntawd, nws yog dej-soluble heev. Thaum yaj hauv dej, qhov ionic compound dissociates rau hauv nws cov ions. Qhov no dissolution nyob rau hauv dej yog heev exothermic. Sodium hydroxide yog hygroscopic. Qhov no txhais tau tias, sodium hydroxide tuaj yeem nqus dej vapor thiab carbon dioxide los ntawm huab cua thaum raug huab cua.
Cov ntawv thov ntawm sodium hydroxide suav nrog nws siv hauv kev tsim ntau cov xab npum thiab tshuaj ntxuav tes, tsim cov tshuaj xws li tshuaj aspirin, tswj cov dej acidity, dissolving cov khoom tsis xav tau hauv cov ntoo thaum tsim cov khoom ntoo thiab ntawv, thiab lwm yam.
Qhov txawv ntawm Ammonium Hydroxide thiab Sodium Hydroxide yog dab tsi?
Ammonium hydroxide thiab sodium hydroxide yog ob yam sib txawv inorganic. Ammonium hydroxide yog cov kua uas muaj cov tshuaj formula NH4OH thaum sodium hydroxide yog hlau hydroxide muaj cov tshuaj formula NaOH. Qhov sib txawv tseem ceeb ntawm ammonium hydroxide thiab sodium hydroxide yog tias ammonium hydroxide tshwm sim hauv cov kua hauv lub xeev thaum sodium hydroxide tshwm sim hauv lub xeev khov ntawm chav sov.
Tsis tas li ntawd, lwm qhov sib txawv yooj yim ntawm ammonium hydroxide thiab sodium hydroxide yog tias ammonium hydroxide muaj cov ntxhiab tsw tsw, thaum sodium hydroxide tsis muaj ntxhiab.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm ammonium hydroxide thiab sodium hydroxide hauv daim ntawv.
Summary – Ammonium Hydroxide vs Sodium Hydroxide
Ammonium hydroxide yog cov kua tshuaj muaj cov tshuaj formula NH4OH. Sodium hydroxide yog hlau hydroxide muaj cov tshuaj formula NaOH. Qhov sib txawv tseem ceeb ntawm ammonium hydroxide thiab sodium hydroxide yog tias ammonium hydroxide tshwm sim hauv cov kua hauv lub xeev thaum sodium hydroxide tshwm sim hauv lub xeev khov ntawm chav sov.
