Tūponotanga
Mura:E ai ki ngā paerewa ā-motu, he mea mura te konutai dithionite ina mākū. Ka tauhohe kaha ina pā ki te wai, ka puta he hau mura pērā i te hauwai whanariki me te hauhā whanariki, ā, ka tukuna he nui te wera. Ko te whārite tauhohenga ko: 2Na2S2O4+2H2O+O2=4NaHSO3, ā, ka tauhohe anō ngā hua ki te whakaputa hauwai whanariki me te hauhā whanariki. He āhua waenga te hauhā o te konutai dithionite, ā, he koretake ōna āhuatanga matū. He kaha te whakaiti. Ina tūtaki ki ngā waikawa waikura kaha, pērā i te waikawa whanariki, te waikawa perchloric, te waikawa nitric, te waikawa phosphoric me ētahi atu waikawa kaha, ka pāngia ngā mea e rua e te tauhohenga redox, ā, he kaha te tauhohenga, ka tukuna he nui te wera me ngā matū paitini. Ko tōna whārite tauhohenga ko: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Te tahunga ā-pūmau:Ko te pūmahana mura ohorere o te konutai dithionite he 250℃. Nā te iti o tōna pūmahana mura, he totoka mura tuatahi (ko te pūmahana mura kei raro iho i te 300℃, ā, ko te pūmahana mura o te pūmahana rewa iti kei raro iho i te 100℃). He tino ngāwari te mura ina pāngia e te wera, te ahi, te waku me te pānga. He tere te tere mura, ā, he nui te tūponotanga ahi. Ka nui ake pea te wāhi mura i te hau hauwai sulfide i puta i te wā o te tukanga mura, ka nui ake te tūponotanga ahi.

Pahūtanga:He paura kōwhai mārama te konutai dithionite. He ngāwari te hanga i tētahi ranunga pahū i te rangi. Ka puta te pahūtanga puehu ina tūtaki ki tētahi pūtake ahi. He pahūtanga te ranunga o te konutai dithionite me te nuinga o ngā waikura, pērā i te chlorates, te nitrates, te perchlorates, te permanganates rānei. Ahakoa kei te aroaro o te wai, ka pahū i muri i te waku iti, i te pānga rānei, inā koa i muri i te pirau wera, ka tae te hau mura i puta i muri i te tauhohenga ki te rohe pahūtanga, kātahi ka nui ake te tūponotanga pahūtanga.
