Oxidation xeev hauv SO3 (g) yog: Sulfur (+6) & Oxygen (-2), vim SO3 (g) tsis muaj nqi. Txawm li cas los xij hauv (SO3) 2 - (aq) Oxidation xeev yog: Sulfur (+4) & Oxygen (-2). Tsis txhob muab ob qho tsis meej pem, lawv tuaj yeem sau tau yam tsis tau them nqi, tab sis yog tias SO3 yog (aq) nws yuav muaj nqi ntawm - 2.

Tsis tas li ntawd, dab tsi yog lub xeev oxidation ntawm sulfur hauv so2?

+4

Ib sab saum toj, dab tsi yog lub xeev oxidation ntawm sulfur atoms hauv s2o42? Cov pa oxygen tam sim no hauv cov molecule muaj tus nqi ntawm -12 tag nrho ua ke (-2 X 6). Thiab kom tau mus rau tus nqi ntawm -2, nws yuav tsum tau Sulfur kom muaj tus nqi tag nrho ntawm +10. Qhov no faib los ntawm 4 atoms txhais tau hais tias Sulfate ion muaj tus nqi ntawm + 2.5!

Ib yam li ntawd, nws yog nug, dab tsi yog lub xeev oxidation ntawm leej faj?

Sulfur khoom pov thawj oxidation tus lej ntawm -2, 0, +2, +4 thiab +6. Oxidation naj npawb -2 pom nyob rau hauv sulfide ion, S--, thiab ib qho kev sib xyaw ua ke yog H2S, hydrogen sulfide los yog hydrosulphuricacid.

Dab tsi yog cov lej ntawm tag nrho cov lej oxidation hauv ib qho kev sib xyaw?

Tus lej ntawm oxidation tooj nyob rau hauv nruab nrab compoundis zero. 10. Cov lej ntawm oxidation nyob rau hauv ib lub polyatomic ionis sib npaug rau tus nqi ntawm cov ion. Tus lej oxidation ntawm cov sulfur atom hauv SO42- ion yuav tsum yog +6, rau piv txwv , vim tias cov lej ntawm oxidation ntawm cov atoms hauv cov ion no yuav tsum sib npaug -2.
