Qhov sib txawv tseem ceeb ntawm ferric thiab ferrous sulphate yog tias ferric sulphate muaj hlau nyob rau hauv +3 oxidation lub xeev, whereas ferrous sulphate muaj hlau nyob rau hauv lub +2 oxidation xeev.
Ferric thiab ferrous sulphate yog sulphates ntawm hlau. Lawv yog cov ionic compounds uas muaj cations (hlau nyob rau hauv txawv oxidation xeev) thiab anions (sulphate anions). Cov tshuaj formula ntawm ferric sulphate yog Fe2(SO4)3 thaum cov tshuaj formula ntawm ferrous Sulfate yog FeSO4
Ferric Sulphate yog dab tsi?
Ferric sulphate yog ib qho tshuaj sulfate uas muaj cov tshuaj Fe2(SO4)3 Cov hlau hauv qhov sib xyaw no yog nyob rau hauv +3 oxidation xeev. Lub npe tshuaj yog hlau (III) sulphate. Nws yog dej-soluble thiab feem ntau tshwm nyob rau hauv yellowish-grey xim muaju. Muaj daim ntawv tsis muaj dej thiab qee cov ntawv hydrated. Cov molar loj ntawm daim ntawv anhydrous yog 399.9 g / mol. Txawm li cas los xij, daim ntawv anhydrous tsis tshua muaj tshwm sim hauv qhov xwm txheej. Daim ntawv pentahydrate (muaj tsib lub molecules dej txuam nrog ib qho ferric sulphate molecule) yog daim ntawv ntau tshaj.

Nyob hauv cov txheej txheem tsim khoom, cov khoom sib xyaw no tau txais los ua cov tshuaj es tsis yog cov khoom. Kev tsim khoom loj loj suav nrog kev kho sulfuric acid nyob rau hauv lub xub ntiag ntawm ferrous sulphate thiab oxidizing tus neeg sawv cev (xws li chlorine, nitric acid, thiab lwm yam)
Ferrous Sulphate yog dab tsi?
Ferrous sulphate yog ib qho sulphate ntawm cov hlau uas muaj cov tshuaj formula FeSO 4 Cov hlau hauv cov khoom no yog nyob rau hauv lub xeev +2 oxidation. Lub npe tshuaj ntawm ferrous sulphate yog hlau (II) sulphate. Muaj ob daim ntawv anhydrous thiab hydrated forms. Daim ntawv tshaj plaws yog daim ntawv heptahydrate. Nws muaj xya dej molecules txuam nrog ferrous sulphate molecule. Daim ntawv heptahydrate no tshwm sim li xiav-ntsuab crystals.

Ferrous sulphate yog lag luam npaj los ntawm oxidation ntawm pyrite. Txawm li cas los xij, lwm txoj hauv kev uas tsim cov khoom sib xyaw no hauv ntau qhov ntau raws li cov khoom lag luam yog kev ua tiav ntawm cov hlau. Ntawm no, cov ntawv hlau hla dhau ntawm lub da dej uas muaj sulfuric acid.
Qhov txawv ntawm Ferric thiab Ferrous Sulphate yog dab tsi?
Ferric thiab ferrous sulphate yog sulphates ntawm hlau. Qhov sib txawv tseem ceeb ntawm ferric thiab ferrous sulphate yog ferric sulphate muaj hlau nyob rau hauv lub xeev +2 oxidation, whereas ferrous sulphate muaj hlau nyob rau hauv lub +3 oxidation xeev. Ferric sulphate yog sulphate ntawm hlau uas muaj cov tshuaj formula Fe2(SO4)3 thaum ferrous sulphate yog ib tug sulphate ntawm hlau uas muaj cov tshuaj formula FeSO4 Cov ntaub ntawv anhydrous ntawm cov tebchaw no tsis tshua muaj; Yog li ntawd, peb tuaj yeem nrhiav tau ntau hom hydrated daim ntawv ntawm ferric sulphate raws li daim ntawv pentahydrated; Feem ntau hom ferrous sulphate yog daim ntawv heptahydrate.
Tsis tas li ntawd, feem ntau hydrated daim ntawv ntawm ferric sulphate tshwm nyob rau hauv yellowish-grey crystals thaum ferrous sulphate tshwm nyob rau hauv xiav-ntsuab crystal daim ntawv. Yog li, qhov no yog qhov sib txawv yooj yim ntawm ferric thiab ferrous sulphate. Thaum xav txog cov txheej txheem tsim khoom, peb tuaj yeem tsim ferric sulphate los ntawm kev kho sulfuric acid nyob rau hauv lub xub ntiag ntawm ferrous sulphate thiab oxidizing tus neeg sawv cev (xws li chlorine, nitric acid, thiab lwm yam). Lub caij no, peb tuaj yeem tsim ferrous sulphate ntawm oxidation ntawm pyrite. Txawm li cas los xij, lwm txoj hauv kev uas tsim cov khoom sib xyaw no hauv ntau qhov ntau raws li cov khoom lag luam yog kev ua tiav ntawm cov hlau.
Summary – Ferric vs Ferrous Sulphate
Ferric thiab ferrous sulphate yog sulphates ntawm hlau. Qhov sib txawv tseem ceeb ntawm ferric thiab ferrous sulphate yog ferric sulphate muaj hlau nyob rau hauv +2 oxidation lub xeev, whereas ferrous sulphate muaj hlau nyob rau hauv lub +3 oxidation xeev.
