Sulfate ntawm manganese (II) lossis manganese sulfate yog cov ntsev inorganic ntawm sulfuric acid thiab manganese, uas muaj oxidation xeev ntawm 2+. Nws kuj yog qee zaum hu ua manganese sulfate. Cov tshuaj formula ntawm manganese sulfate yog MnSO4. Hauv qhov xwm txheej, nws tshwm sim raws li crystalline hydrates hauv qee cov zaub mov: smikite (monohydrate), ilesite (tetrahydrate), jococuite (pentahydrate), mallardite (heptahydrate).
Tau txais
Tau cov ntsev no los ntawm kev yaj manganese (II) oxide lossis manganese carbonate hauv sulfuric acid.
MnO + H2SO4=MnSO4 + H 2O
MnCO3 + H2SO4=MnSO4 + H2O + CO2
Manganese oxide yog cov khoom siv raw zoo, yog li yuav luag tag nrho cov manganese sulfate tau txais los ntawm txoj kev no.
Nws tuaj yeem tau txais los ntawm leaching txo ore nrog ammonium sulfate. Nws kuj yog ib qho khoom los ntawm kev ua cov manganese carbonate ore.
Lub cev muaj zog
Manganese sulfate yog cov hmoov tsis muaj xim crystalline. Nws cov kev daws teeb meem muaj ib qho xim liab me ntsis, vim yog tsim ntawm aqua complex nrog manganese [Mn(Н2O)62+ . Yooj yim soluble hauv dej, me ntsis hauv cawv thiab ethylene glycol. Qhov siab tshaj plaws solubility yog mus txog ntawm 25 ° C. Melting point - 700 ° C, ntawm 850 ° C nws decomposes rau hauv oxides ntawm sulfur thiab manganese. Qhov ceev ntawm crystals ntawm 20 ° C yog 3.25g / cm 3. Nws yog paramagnet, i.e. magnetized nyob rau sab nraud magnetic teb.
tuaj yeem nqus dej los tsim cov dej crystalline nrog 1, 4, 5 lossis 7 dej molecules. Cov crystalline hydrates no yog xim liab thiab muaj lub cev sib txawv me ntsis los ntawm anhydrous manganese sulfate. Txhua tus ntawm lawv muaj nws tus kheej kub ntau yam uas nws yuav ruaj khov tshaj plaws: monohydrate - tsuas yog siab dua 200 ° C, tetrahydrate - ntawm 30-40 ° C, pentahydrate - 9-25 ° C, heptahydrate - tsuas yog qis dua 9 ° C. Yuav luag tag nrho cov crystalline hydrates erode nyob rau hauv huab cua (poob dej thiab tawg), tshwj tsis yog rau cov tetrahydrate.
tshuaj muaj zog
Vim tias cov manganese hauv cov ntsev no muaj cov oxidation qis tshaj plaws (+2), cov ntsev no tuaj yeem ua tus neeg sawv cev txo qis thiab cuam tshuam nrog cov neeg muaj zog oxidizing:
2MnSO4 + 8HNO3 + 5PbO2=2HMnO 4 + 4Pb(NO3)2 + Pb(HSO4) 2 + 2H2O
Reacts nrog alkalis, nrog nag lossis daus:
MnSO4 + 2KOH=Mn(OH)2↓ + K2SO4
Hlau manganese tuaj yeem tau los ntawm electrolysis ntawm kev daws manganese sulfate:
2MnSO4 + 2H2O=2Mn↓ + O2 + 2H 2SO4
Daim ntawv thov
Hauv kev tsim tshuaj, cov ntsev no yog siv kom tau cov manganese ntshiab thiab nws lwm cov tebchaw. Nws kuj tseem siv tau los ua kev tshuaj ntsuam reagent. Hauv kev lag luam khoom noj thiab tshuaj, nws yog kev noj zaub mov ntxiv (rau tib neeg thiab tsiaj txhu). Nws kuj yog ib qho catalyst hauv cov organic synthesis. Cov ntaub ntawv qhia ntxaws ntxaws ntawm cov khoom no muaj nyob hauv ntau yam GOSTs. Manganese sulfate yog siv nyob rau hauv kev lag luam textile ua ib feem ntawm dyes rau fabrics thiab porcelain.
Kev siv tseem ceeb ntawm manganese sulfate yog chiv. Manganese thiab sulfur yog cov ntsiab lus tseem ceeb rau cov nroj tsuag kev loj hlob, thiab nyob rau hauv no compound lawv yog nyob rau hauv ib tug heev yooj yim daim ntawv rau lawv, vim hais tias manganese sulfate yog heev soluble nyob rau hauv dej.
Ntau txog kev siv chiv
Cov chiv no tuaj yeem siv tau rau yuav luag txhua cov nroj tsuag thiab ntawm txhua qhov av. Sandy thiab hav zoov av xav tau kev siv cov chiv no. Ua tib zoo nws yog tsim nyog nce qhov concentration ntawm manganese ntawm chernozems thiaj li yuav tiv thaiv ib tug overabundance ntawm lub caij no. Qhov no tuaj yeem ua rau intoxication ntawm cov nroj tsuag thiab cov tsos ntawm me ntsis ntawm cov npoo ntawm nplooj. Tab sis nws yuav tsum tau borne nyob rau hauv lub siab hais tias av acidity cuam tshuam tus nqi ntawm ntsev dissolution: nyob rau hauvHauv cov av acidic, manganese sulfate dissolves qeeb dua, uas txhais tau tias nws maj mam nqus los ntawm cov nroj tsuag. Yog li ntawd, ua ntej thov chiv, nws yog ntshaw kom deoxidize cov av nrog limestone.
Manganese vitriol qualitatively thiab quantitatively nce qoob loo yields, raws li manganese pab kom chlorophyll cov ntsiab lus nyob rau hauv cov nroj tsuag. Nrog nws qhov tsis muaj peev xwm, chlorosis, fusarium, xim av thiab xim av xeb tshwm sim: cov nplooj me dhau los ua me me thiab me me tshwm rau ntawm lawv, thiab cov laus ua daj ntseg thiab daj ntawm cov leeg. Xws li nplooj sai sai tuag tawm, uas yog vim li cas cov nroj tsuag qeeb hauv kev loj hlob thiab flowering. Qee cov qoob loo txwv tsis pub cov qoob loo tag nrho.
Feem ntau, manganese sulfate yog siv ua ke nrog nitrogen, phosphorus thiab potash chiv. Nws nce lub peev xwm ntawm cov nroj tsuag kom nqus tau lwm yam khoom noj tseem ceeb: potassium, nitrogen thiab phosphorus. Nws kuj ua rau cov piam thaj ntau ntxiv hauv cov qoob loo. Qhov no yog qhov tseeb tshwj xeeb ntawm cov hauv paus qoob loo, berries thiab zaub. Cov kua txiv hmab txiv ntoo uas tau los ntawm cov txiv hmab txiv ntoo no muaj cov acidity tsawg. Tag nrho cov no muaj txiaj ntsig zoo rau lub txee lub neej ntawm cov txiv hmab txiv ntoo.
Cov chiv no muaj lwm yam khoom muaj txiaj ntsig: nws tsis raug ntxuav tawm los ntawm nag lossis daus, yog li nyob hauv av kom ntev. Qhov no ua rau cov nyhuv ntawm cov chiv ntev. Thaum siv hauv tsev cog khoom, nws raug nquahu kom siv cov chiv rau hauv daim ntawv ntawm kev daws nrog cov concentration tsis siab tshaj 0.2%. Nws yog qhov zoo tshaj rau dej fertilized nroj tsuag nrog dej ntawm qhov kub ntawm 20-25 ° C, vim ntsev dissolves zoo tshaj plaws.raws nraim hauv lub sijhawm no.
Kev nyab xeeb
Manganese sulphate yog cov tshuaj lom. Ntxiv mus, ob qho tib si anhydrous thiab nws cov crystalline hydrates. Thaum noj, nws ua rau mob hnyav heev, uas tuaj yeem ua rau puas tsuaj rau lub paj hlwb thiab lub plab zom mov, nrog rau lub hlwb. Thaum nws los rau ntawm daim tawv nqaij, dermatitis thiab eczema tshwm sim, uas nyuaj heev rau kho.
Thaum ua haujlwm nrog cov tshuaj no, nws yuav tsum tau npog cov tawv nqaij, nco ntsoov hnav hnab looj tes roj hmab thiab lub tshuab ua pa. Chav tsev yuav tsum muaj qhov cua zoo lossis muaj qhov cua nkag, nrog rau kev soj ntsuam tas li kom pom qhov siab tshaj plaws ntawm manganese hauv huab cua. Manganese sulfate yuav tsum muab cia rau hauv lub ntim ntim nkaus xwb.
