NH4 + muaj tus nqi + vim nws yog NH3 uas tau tsim nrog H + siv N ib khub. Tag nrho cov ion muaj 1 ntau proton tshaj nws muaj electrons li no tus nqi.

Kuj tseem paub yog, vim li cas ammonium zoo?

Cov zoo them H + ion, los yog proton, isattracted rau ib leeg khub ntawm qhov tsis zoo kawg ntawm lub ammonia dipole. Qhov txawv tab sis qhov tseem ceeb yog qhov ammonium ion muaj ib tug ntxiv proton nyob rau hauv lub nucleus ntawm lub nruab nrab atom thiab li no tag nrho cov nqi ntawm +1.

Tsis tas li ntawd, puas yog ammonia zoo lossis tsis zoo? Ammonia yog ib tug polar molecule: Saib daim duab ntawm sab laug. Lub trigonal pyramid geometry nrog ib leeg electron khub pab txhawb rau cov nyhuv. Theelectrostatic muaj peev xwm qhia tau meej tias cov nitrogen yog ib feem tsis zoo hos cov hydrogens yog ib feem zoo.

Tom qab ntawd, vim li cas nh4 yog ion?

Ammonium ions , NH4+ , yog tsim los ntawm kev hloov ntawm hydrogen ion los ntawm hydrogen chloride mus rau thelone khub ntawm electrons ntawm ammonia molecule. Cov hydrogen'selectron tau tso tseg ntawm cov tshuaj chlorine los tsim cov tshuaj tsis zoo chloride ion.

Puas yog nh4+ yog acid lossis base?

Yog li, NH3 yog a puag thiab H2O yog ib qho kua qaub . Ib kua qaub – puag Cov tshuaj tiv thaiv yog suav tias yog ib qho kev hloov pauv proton (H +) cov tshuaj tiv thaiv. - Hom NH4 + thiab NH3 yog aconjugate kua qaub - puag khub.
