Ukukhanya okuncane kwe-ammonia amanzi
2024.09.02
Izindlela zokugcina zokugcina zikhona ezindaweni zase-ammonia:
NH3+H2O=(okuyizinkanyezi)=NH3 · H2O
NH3 · H2O=(reversible)=NH4++OH- translates to "NH3 · H2O=(okuzimisela)=NH4++OH-" in isiZulu.
Ngakho, kuphela isilinganiso esincane sika amamoniya amakhemikali ezithinta namanzi ukuze sikhulekele amaqembu we-ammonium NH4+ kanye nezinto zama-hydroxide OH-, ekwenzela ukukhanya okuncane.
Ammonia amanzi inamakhemikhali alkaline:
Iningi labo abasebenzisi abanamakhemikhali abakhona abasebenzisa le ndlela ekulawuleni ukuthi kungaba khona i-NH3.
Izakhiwo zingathatha ngesifo ukuze zizalwe izithelo zase-ammonium. Uma i-ammonia enzima ethuthukile ikhona nezithelo ezithuthukile njengoba i-hydrochloric acid ethuthukile kanye ne-nitric acid ethuthukile, iyakwazi ukwenza umlotha omhlophe.
NH3 + HCl = NH4Cl (isibukwane esimhlophe)
NH3+HNO3=NH4NO3 (umlotha omhlophe)
Kodwa, le nto ayikwazanga ukwenza xa isithuthi esingavuthi njengase sulfuric acid no phosphoric acid. Lolu hlobo lwezinto lweza kusetshenziswa ekilabhu ukuze kwenziwe ukubonakala kwesimo sokuwela kweNH3 noma amanzi we-ammonia.
Eminye imboni, ukuphakama okuncane kwe-ammonia water kuyinto esetshenziswa ukulawula isulfuric acid yomoya wasekhaya wokuphefumula kanye nokuphinda ukulimala kwangaphandle.
SO2+2NH3 · H2O=(NH4) 2SO3+H2O translates to SO2+2NH3 · H2O=(NH4) 2SO3+H2O
(NH4)2SO3 + SO2 + H2O = 2N4HSO3 (NH4)2SO3 + SO2 + H2O = 2N4HSO3
