Ferrous sulfate

nkowa nkenke:

Ferrous sulfate bụ ihe inorganic, crystalline hydrate bụ heptahydrate na nkịtị okpomọkụ, nke a na-akpọkarị "green alum", ìhè green crystal, weathered na akọrọ ikuku, n'elu oxidation nke aja aja isi sulfate n'ikuku ikuku, na 56.6 ℃ na-tetrahydrate, na 65 ℃ na-aghọ monohydrate. Ferrous sulfate na-agbaze n'ime mmiri ma ọ fọrọ nke nta ka ọ ghara ịsacha ya na ethanol. Ngwọta mmiri ya na-eji nwayọọ nwayọọ na-ekpo ọkụ na ikuku mgbe oyi na-atụ, na oxidizes ngwa ngwa mgbe ọ na-ekpo ọkụ. Ịtinye alkali ma ọ bụ ikpughe na ìhè nwere ike mee ka oxidation ya dịkwuo elu.
