Ferrous sulfate heptahydrate, nke a na-akpọkarị akwụkwọ ndụ akwụkwọ ndụ alum, bụ ihe na-adịghị ahụkebe nke nwere usoro FeSO4·7H2O. A na-ejikarị ya eme ihe n'imepụta nnu ígwè, ink, magnetik iron oxide, ihe na-eme ka mmiri dị ọcha, ihe na-egbu nje, ihe na-akpali ígwè; A na-eji ya dị ka agba coal, ihe na-eme ka tanning dị ọcha, ihe na-eme ka ihe dị ọcha, ihe na-echekwa osisi na ihe mgbakwunye fatịlaịza mejupụtara ya, na nhazi ferrous sulfate monohydrate. A na-ewebata ihe ndị dị na ya, ngwa ya, nkwadebe ya na nchekwa ya na ferrous sulfate heptahydrate n'akwụkwọ a.
Okike
Ferrous sulfate heptahydrate bụ kristal na-acha anụnụ anụnụ nke nwere sistemụ kristal na-agbanwe agbanwe dị mma yana nhazi hexagonal nke nwere ihe mejupụtara ya.
Ọ dị mfe ịhapụ mmiri kristal n'ikuku wee ghọọ sulfate ferrous anhydrous, nke nwere ike ibelata ike na oxidation.
Mmiri mmiri ya na-eme ka ọ dị ka acid n'ihi na ọ na-agbaze n'ime mmiri iji mepụta asịd sulfuric na ion ferrous.
Ọkụ ferrous sulfate heptahydrate nwere njupụta nke 1.897g/cm3, ebe agbaze nke 64°C na ebe esi mmiri nke 300°C.
Ọ dịghị mma ma ọ bụrụ na okpomọkụ ya adịghị ike, ọ dịkwa mfe ịgbari n'oge okpomọkụ dị elu iji mepụta gas ndị na-emerụ ahụ dịka sulfur dioxide na sulfur trioxide.
Ngwa
A na-ejikarị ferrous sulfate heptahydrate eme ihe n'ọtụtụ ụlọ ọrụ.
Nke mbụ, ọ bụ isi iyi dị mkpa nke ígwè, nke enwere ike iji kwadebe ihe ndị ọzọ dị na ígwè, dịka ferrous oxide, ferrous hydroxide, ferrous chloride, wdg.
Nke abụọ, enwere ike iji ya kwadebe kemịkalụ dịka batrị, agba, ihe na-akpali akpali, na ọgwụ nje.
Tinyere nke ahụ, enwere ike iji ya mee ihe na ọgwụgwọ mmiri mkpofu, desulfurization, nkwadebe fatịlaịza phosphate na akụkụ ndị ọzọ.
Mkpa nke ferrous sulfate heptahydrate pụtara ìhè, o nwekwara ọtụtụ ojiji na mmepụta ụlọ ọrụ mmepụta ihe.
Ụzọ nkwadebe
E nwere ọtụtụ ụzọ esi eme nkwadebe nke ferrous sulfate heptahydrate, usoro ndị a na-ejikarị eme ihe bụ ndị a:
1. Nkwadebe nke sọlfọlik acid na ntụ ferrous.
2. Nkwadebe nke sulfuric acid na mmeghachi omume ingot ferrous.
3. Nkwadebe nke sọlfọlik acid na ammonia ferrous.
E kwesịrị ịmara na a ga-achịkwa ọnọdụ mmeghachi omume nke ọma n'oge nkwadebe iji zere gas ndị na-emerụ ahụ na mfu ndị na-enweghị isi.
Nchekwa
Ferrous sulfate heptahydrate nwere ihe egwu ụfọdụ, ịkwesịrị ịṅa ntị na ihe ndị a:
1. Ferrous sulfate heptahydrate bụ ihe na-egbu egbu, ekwesighi imetụ ya aka ozugbo. E kwesịrị izere iku ume, iri ya na imetụ ya aka na akpụkpọ ahụ na anya.
2. N'ịkwadebe na iji ferrous sulfate heptahydrate, a ga-akpachara anya iji gbochie gas na ihe egwu ọkụ na mgbawa.
3. N'oge nchekwa na njem, a ga-eleba anya ka e zere imetụ kemịkalụ dịka oxidants, acids na alkalis aka iji zere mmeghachi omume na ihe mberede.
Nchịkọta
Na nchịkọta, ferrous sulfate heptahydrate bụ ihe dị mkpa na-adịghị arụ ọrụ nke ọma ma nwee ọtụtụ ojiji dị iche iche.
N'ime mmepụta ụlọ ọrụ mmepụta ihe na ụlọ nyocha, a ga-elebara ihe egwu dị na ya anya, a ga-emekwa ihe kwesịrị ekwesị maka nchekwa, njem na ojiji iji hụ na nchekwa onwe onye na nchekwa gburugburu ebe obibi.
N'otu oge ahụ, a ga-eleba anya n'ichekwa akụrụngwa n'usoro ojiji iji zere ihe mkpofu na mmetọ.
