Cov molecular qauv rau sulfate yog SO42-. Plaub daim ntawv cog lus, ob qho tib si thiab ob ob, yog sib koom ntawm cov sulfur thiab oxygen atoms. Qhov-2 koj pom ntawm lub sulfate ion ceeb toom koj tias qhov molecule no raug them. Qhov no tsis zoo nqi los ntawm cov pa atoms uas nyob ib puag ncig cov sulfur atom.

Ua li no, lub cim thiab nqi rau sulfide yog dab tsi?

Sulfide. Ib qho sulfide ion yog tsim los ntawm ib leeg sulfur atom . Nws tus nqi yog qhov tsis zoo ob, muab sulfides no mis: S^2-. Sulfide ions yog qhov yooj yim heev.

Qhov thib ob, vim li cas sulfate thiaj li muaj nqi? Sulfate anion muaj -2 nqi los yog nws tuaj yeem hais tias net oxidation tsis muaj ion yog -2. Nws muaj -2 kos npe vim tsis raug cai nqi ntawm oxygen. Kev cai nqi ntawm ib qho atom = tus naj npawb ntawm nws valence electron ua ntej kev sib txuas - tus naj npawb ntawm nws valence electron tom qab sib txuas.

Raws li txoj cai, tus nqi ntawm sulfate yog dab tsi?

Sulfate ion muaj ob lub qauv siv tau uas koj tuaj yeem kos tau, ib qho nrog sulfur muaj cov qauv nqi ntawm xoom thiab ib tug nrog sulfur muaj ib tug formal nqi ntawm +2.

Dab tsi yog sulfur nqi hauv so42 -?

Ib qho S atom muaj 6 valence electrons thiab O atom muaj 6 qhov kev xaiv tsa. SO4 => (6x1) + (6x4) = 30 valence electrons. Peb xav tau 32 valence electrons rau 4 lub plhaub sab nraud (8x4) tab sis tsuas muaj 30. nqi yog 2- rau ion.
