Oxalic acid

Oxalic acidbụ ihe anụ ahụ. Mpempe kemịkal bụ h₂c₂o₄. Ọ bụ ngwaahịa nke nje metabolics. Ọ bụ akụkụ abụọ adịghị ike acid. A na-ekesa ya ebe niile na osisi, anụmanụ, na ahụ fungal. Ọ na-arụ ọrụ dị iche iche na ihe dị iche iche dị ndụ. Ya mere, a na-ewere acid acid dị ka onye na-emegide ya maka nnabata na itinye mmiri nke ịnweta. Ya arthydride bụ carbon vioxide.

Njirimara:Mpempe akwụkwọ nke monoclinic ma ọ bụ prismatic kristal ma ọ bụ ntụ ntụ, oxalic acid odo na-enweghị atụ site na oxalic und. Sublimition na 150 ~ 160 ℃. Enwere ike ihu ya ikuku na ikuku na-ekpo ọkụ. 1g na-soluble na 7ml mmiri, 2ml etsing, 1.8ml ettanol, 100ml ether, 100ml glycerin, na cloroform na mmanụ. 0.1mol / l ngwọta nwere pH nke 1.3. Nnọọ ezigbo (mmiri = 1) bụ 1.653. Na-agbaze 49.5 ℃.

Ngwongwo kemịkal:Oxalic acid, nke a makwaara dị ka glycolic acid, a na-ahụkarị nri osisi. Oxalic acid bụ poring kristal na-enweghị agba, na-agbanye na mmiri kama na ndọpụ ahịhịa dị ka ether,

Okele nwere mmetụta ọ na-arụ ọrụ ma ọ bụ ụdị onye ọrụ na-echepụta ọla ọzọ na nri osisi. Mgbe ejikọtara acid acid na ihe ụfọdụ alkaline ụwa, a na-ebelata akụkụ ya nke ukwuu, dị ka calcium oxium fọrọ nke nta ka ọ ghara imikpu ya. Ya mere, ọnụnọ nke acid acid nwere nnukwu mmetụta na biopailability nke mineral; Mgbe ejikọtara oxlic acid na ụfọdụ ntụgharị usoro, a na-etolite gburugburu ebe a na-eme ihe ngosi maka nhazi nke oxalic acid, na nke a na-amụba nke ukwuu.

Oxalic acid malitere sublice na 100 ℃, sublimated ngwa ngwa na 125 ℃, ma na-amanye ya nke ọma na 157 ℃, wee malite decompose.
