Ngā Paerewa Kounga mō te Waikawa Oxalic (Paerewa ā-Motu)
Ko te waikawa oxalic, e mōhiotia ana ko te waikawa ethanedioic, ko tōna hanganga HOOCCOOH me te papatipu molar o te 126.07. Ko te nuinga o te wā kei roto hei dihydrate, ka puta hei tioata mārama kore tae, hei paura mā rānei, kāore he kakara me te reka kawa. E rua ngā āhua tioata: te āhua-α (rhombic) me te āhua-β (monoclinic). Ko ō rātou ira rewa me te kiato whanaunga (i te 17°C/4°C) ko: te āhua-α i te 189.5°C me te kiato o te 1.900; te āhua-β i te 182°C me te kiato o te 1.895. Ina pāngia e te hau maroke, ina werahia rānei, ka ngaro tōna wai tioata. He pūngāwerewere te waikawa oxalic, ā, ka tere te whakangawari: ka tīmata te whakangawari i te 100°C, ka tere te whakangawari i te 125°C, ā, ka tino whakangawari i te tīmatanga o te pirau i te 157°C. Ka wairewa i roto i te wai wera me te etanoru, he paku wairewa i roto i te wai matao, he iti noa te wairewa i roto i te diethyl ether, ā, kāore e wairewa i roto i te benzene me te chloroform. Hei waikawa waro kaha, ka pāngia te waikawa oxalic e ngā tauhohenga whakakorekore me ngā kawakore.
