Kedu ihe dị iche n'etiti acid na oxalic Asịd Asịd?
Iji mata ọdịiche dị n'etiti oxalic acid na acetic acid, anyị nwere ike iji ha tụnyere site n'ọtụtụ akụkụ dịka ọdịdị kemịkalụ, ihe ndị dị na ya, na ojiji bara uru. Ọ bụ ezie na ha abụọ bụ nke organic acid, ọdịiche dị n'ụdị na njirimara ha na-eduga n'omume dị iche iche n'okike, mmeghachi omume kemịkalụ, na ojiji mmadụ.

Nke mbụ, ka anyị leba anya n'ihe mejupụtara kemịkalụ ha.
Asịd Oxalic, nke a maara dịka ethanedioic acid nke ọma, nwere otu carboxyl abụọ (-COOH) n'ime nhazi molekul ya, ya na usoro molekul H₂C₂O₄. Ọ dị ka molekul nwere otu acid abụọ, dị njikere iwepụta ion hydrogen abụọ.

Acetic acid, nke a makwaara dị ka ethanoic acid, nwere naanị otu otu carboxyl, yana usoro molekul CH₃COOH. Mkpụrụ ndụ ihe nketa ya dị ka "onye njem naanị ya" nwere otu otu acidic. Ọdịiche a na nhazi molekul, dị ka "koodu mkpụrụ ndụ ihe nketa ha", na-ekpebi usoro ọdịiche omume ndị na-esote.

Ihe kacha pụta ìhè na "ọdịiche mkpụrụ ndụ ihe nketa" a bụ ike acid.
Oxalic acid bụ asịd siri ike nke nwere ike ime ka ion hydrogen dị n'ime mmiri, na-eme ka acid ya sie ike karịa nke acetic acid.

Acetic acid bụ asịd na-adịghị ike nke monoprotic nkịtị; naanị ụfọdụ n'ime molekul ya na-agbanwe n'ime mmiri, na-eme ka ọ bụrụ obere asịd.
Anyị nwere ike iche na oxalic acid bụ onye ntorobịa nwere ume na mmeghachi omume, ebe acetic acid dị ka okenye dị nwayọọ ma nwee njide onwe ya.

Maka ihe ndị metụtara kemịkalụ, n'ihi njikọ kpọmkwem nke otu carboxyl abụọ ya, oxalic acid nwere ike ibelata ike ya. A na-eme ka ọ dị mfe site na ihe ndị na-eme ka oxidizing (dị ka potassium permanganate) mepụta carbon dioxide na mmiri. Àgwà a na-eme ka oxalic acid bụrụ ihe a na-ejikarị eme ihe dị ka ihe na-ebelata ihe na nyocha kemịkalụ.

N'ụzọ dị iche, usoro molekul nke acetic acid kwụsiri ike, ọ naghị adị mfe iwepụ ya ngwa ngwa, na-eme ka ọ bụrụ kemịkal "na-adịgide adịgide".
Ọzọkwa, mgbe oxalic acid meghachiri omume na ụfọdụ ion ígwè (dị ka ion calcium), ọ na-emepụta ihe ndị na-eme ka calcium oxalate ghara ịgbaze nke ọma na mmiri, nke bụ otu n'ime ihe ndị bụ isi mejupụtara nkume akụrụ.
Dịka e si tụnyere ya, a na-agbazekarị acetates site na mmeghachi omume nke acetic acid na calcium ion na ihe ndị ọzọ na mmiri.

Maka ihe na-eme na ojiji, nke ọ bụla nwere ihe ọ na-elekwasị anya na ya.
A na-ahụ Oxalic acid n'ọtụtụ osisi dị iche iche n'okike, dịka spinach, amaranth, na rhubarb. Ọ bụ ya mere a na-atụ aro ka a tee akwụkwọ nri ndị a mmiri tupu e rie ha iji wepụ akụkụ nke oxalic acid ahụ. O nwere ọtụtụ ihe eji eme ya n'ụlọ ọrụ mmepụta ihe, gụnyere iwepụ nchara, ịcha ákwà, na ikewapụ na ịsacha ọla dị ụkọ. Agbanyeghị, n'ihi nsí na ire ere ya, a ga-akpachara anya nke ọma mgbe a na-eji ya.

Acetic acid bụ otu n'ime asịd organic a maara nke ọma na ndụ kwa ụbọchị. Ọ bụ isi ihe dị na mmanya vinega, na-eme ka mmanya vinega nwee ụtọ pụrụ iche ya. N'ụlọ ọrụ nri, a na-eji acetic acid eme ihe dị ka ihe na-eme ka acid ghara ịdị mma ma na-echekwa ihe; n'ụlọ ọrụ kemịkalụ, ọ bụ ihe dị mkpa maka imepụta vinyl acetate, eriri acetate, na ihe ndị ọzọ. N'ihi obere acidity ya na obere nsí (n'ime oke oriri kwesịrị ekwesị), a na-eji acetic acid eme ihe nke ọma ma dịkwa nchebe n'ọhịa nri na ọgwụ.
