Nkọwa ngwaahịa

Oxalic acid bụ acid na-adịghị ike.Ionization nke mbụ na-adịgide adịgide Ka1 = 5.9 × 10-2 na usoro ionization nke abụọ mgbe niile Ka2 = 6.4 × 10-5.Ọ nwere mmetụta acidity.Ọ nwere ike wepụ isi ihe, gbanwee ihe ngosi, ma hapụ carbon dioxide site na mmekọrịta ya na carbonates.Na-emeghachi omume na ihe ndị na-eme ihe na-ekpo ọkụ ma na-adị mfe oxidized na carbon dioxide na mmiri.Acid potassium permanganate (KMnO4) ngwọta nwere ike gbanwee ma belata ka ọ bụrụ ion manganese 2-valence.Na 189.5 ℃ ma ọ bụ n'ihu sulfuric acid gbadoro anya, ọ ga-erepịa ka ọ bụrụ carbon dioxide, carbon monoxide na mmiri.H2C2O4=CO2↑+CO↑+H2O.
