Oxalic acidbụ organic acid nwere usoro kemịkalụ nke H₂C₂O₄. A na-ejikarị ya eme ihe na nhicha, iwepụ nchara, nhazi ụlọ ọrụ mmepụta ihe, nyocha kemịkalụ, nhazi ihe ọkụkụ na mpaghara ndị ọzọ. Acidity ya siri ike na ihe nbelata dị mma na-eme ka ọ rụọ ọrụ dị mkpa n'ọtụtụ ọnọdụ. Dịka onye na-eweta oxalic acid, Aojin Chemical ga-ekekọrịta gị kedu ihe eji oxalic acid eme?
Nhicha na iwepụ nchara
1. Iwepụ nchara na ọnụ ọgụgụ ígwè
Oxalic acid nwere ike meghachi omume na nchara (iron oxide) iji mepụta ogige soluble, bụ nke a na-ejikarị ehichapụ ntụpọ nchara n'elu nkume, taịl nile, na osisi; ọ nwekwara ike wepu ọnụ ọgụgụ calcium n'ime ngwá ụlọ ịsa ahụ ma ọ bụ ihe ọkụkụ.
Ịchacha osisi
N'ime nhazi nke ngwaahịa osisi, oxalic acid nwere ike imebi ntụpọ ojii nke mmetọ ion nke ígwè na-emetọ na osisi ma weghachite agba osisi.
Ngwa ụlọ ọrụ mmepụta ihe na kemịkalụ
1. Nhazi ígwè
A na-eji oxalic acid eme ihe maka anodizing nke aluminom iji kwalite nguzogide corrosion elu; enwere ike iji ya dị ka ihe na-amịpụta maka ọla ụwa na-adịghị ahụkebe.
2. Ebipụta akwa na akwa
