Kedu ka sodium sulfate na anhydrous sodium sulfite ga-esi meghachi omume ọnụ?

Sodium sulfate bụ kristal na-acha ọcha, enweghị isi, kristal na-atọ ụtọ ma ọ bụ ntụ ntụ, nke na-abanye n'ime ikuku ngwa ngwa wee ghọọ sodium sulphate.

Sodium sulphate dị oke ọnụ ma enwere ike iji ya na mmepụta nke iko mmiri, iko, enamel, pulp akwụkwọ, igwekota refrigerant, detergent, desiccant, diluent dye, dissecting chemical reagent, pharmaceuticals, wdg.

Anhydrous sodium sulfite bụ ọcha crystalline ntụ ntụ, soluble na mmiri (na 0 ℃, 12.54g / 100ml mmiri; na 80 ℃, 283g / 100ml mmiri), kasị elu solubility bụ banyere 28% na 33.4 ℃, aqueous ngwọta bụ alkaline, na PH uru bụ banyere 9 ~ 9.5. Na-edozi ntakịrị na mmanya na-aba n'anya, nke na-adịghị edozi na chlorine mmiri mmiri, amonia. Ọ na-adị mfe oxidized na sodium sulfate na ikuku, na-erepịakwa na sodium sulphide na elu okpomọkụ. Ọ bụ ihe na-ebelata ike kpụ ọkụ n'ọnụ, enwere ike iji ya na sọlfọ dioxide mepụta sodium bisulphite, ma meghachi omume na acid siri ike iji mepụta nnu kwekọrọ.

Enwere ike ịgwakọta ya na sulfuric acid iji mee SO2 Na2SO3 + H2SO4 = Na2SO4 + H2O + SO2↑

Sodium sulphate na anhydrous sodium sulphite enweghị mmeghachi omume kemịkalụ ọnụ.
