Ferrous sulphate dulphate

Cov lus qhia luv luv:

Ferrous sulfate heptahydrate, feem ntau yog hu ua ntsuab alum, yog ib qho inorganic sib xyaw nrog cov mis feso4S2o. Mas siv rau hauv kev tsim cov hlau ntsev, number case, cov hlau sib nqus oxide, dej huv cov neeg saib xyuas, tshuaj tua kab mob, hlau catalyst; Nws yog siv raws li cov ntsaws, tanning tus neeg sawv cev, cov khoom siv chiv ntxiv, thiab kev teeb tsa thiab kev nyab xeeb ntawm ferrous sulfate tau qhia hauv daim ntawv no.

Tus yeeb yam

Ferrous sulfate heptahydrate yog cov siv lead ua xiav nrog txoj kev hloov pauv crystal thiab ib tus qauv hexagonal kaw.

Ferrous sulfate heptahydrate yog yooj yim kom poob cov roj ua kom huv si hauv huab cua thiab dhau los ua anhydrous ferrous sulfate, uas muaj cov tshuaj tiv thaiv muaj zog thiab oxidation.

Nws cov kua aque yog acidic vim hais tias nws decomposes nyob rau hauv dej los tsim sulfuric acid thiab ferous ions.

Ferrous sulfate heptahydrate muaj qhov ntom ntom ntawm 1.897g / cm3, lub siab melting ntawm 64 ° C thiab ib lub boiling taw tes ntawm 300 ° C.

Nws cov kev ruaj khov stability yog tsis zoo, thiab nws yooj yim los rhuav tshem cov roj cua ntau xws li cov sulphur dioxide thiab sulfur trioxide.

Daim ntawv thov

Ferrous sulfate heptahydrate yog dav siv hauv kev lag luam.

Ua ntej, nws yog qhov tseem ceeb ntawm cov hlau, uas tuaj yeem siv los npaj lwm cov hlau sib txuas, ferrous hydrods, ferlous chloride, thiab lwm yam.

Thib ob, nws tuaj yeem siv los npaj tshuaj lom xws li roj teeb, tuag, catesalys, thiab tshuaj tua kab.

Ib qho ntxiv, nws kuj tseem tuaj yeem siv hauv kev kho dej huv, desulfurization, tshuaj phosphote chiv npaj thiab lwm yam.

Qhov tseem ceeb ntawm ferrous sulfate heptahydrate yog pom tus kheej yog qhov pom tseeb, thiab nws muaj ntau cov kev siv hauv kev lag luam.

Kev npaj txoj kev

Muaj ntau txoj hauv kev rau kev npaj ntawm ferrous sulfate heptahydrate, thiab cov kev sib xws yog li nram qab no:

1. Kev npaj ntawm sulfuric acid thiab ferrous hmoov.

2. Kev npaj ntawm sulfuric acid thiab ferrous ingot cov tshuaj tiv thaiv.

3. Kev npaj ntawm sulfuric acid thiab ferrous ammonia.

Nws yuav tsum raug sau tseg tias cov tshuaj tiv thaiv yuav tsum tau nruj me ntsis tswj tau thaum lub sijhawm npaj kom tsis txhob muaj kev phom sij thiab kev poob haujlwm tsis tseem ceeb.

Kev tsis muaj teeb meem

Ferrous sulfate heptahydrate muaj qee qhov kev pheej hmoo, yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:

1. Ferrous sulfate heptahydrate yog cov tshuaj lom thiab yuav tsum tsis txhob kov ncaj qha. Inhalation, kev noj haus thiab sib chwv nrog tawv nqaij thiab qhov muag yuav tsum tau zam.

2. Hauv kev npaj thiab siv ntawm ferrous sulfate hepthander, kev saib xyuas yuav tsum tau coj los tiv thaiv kev phom sij thiab hluav taws thiab tawg txaus ntshai.

3. Thaum khaws cia thiab kev thauj mus los, saib xyuas yuav tsum tau them kom tsis txhob muaj kuab lom xws li oxidants, acids kom tsis txhob muaj cov kev hloov pauv thiab xwm txheej.

Lub ntsiab

Hauv cov ntsiab lus, ferrous sulfate heptahydrate yog qhov tseem ceeb inorganic compound thiab muaj ntau cov kev siv.

Kev lag luam kev tsim khoom thiab chaw soj ntsuam, saib xyuas yuav tsum tau them rau nws txoj kev pheej hmoo, thiab kev thauj mus los thiab siv kev tiv thaiv kev nyab xeeb thiab ib puag ncig.

Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau kev txuag cov peev txheej hauv cov txheej txheem ntawm kev siv kom tsis txhob muaj pov tseg thiab muaj kuab paug.
