Isigaxa se-#rongalite senziwa kusetshenziswa i-#sodiummetabisulfite, #zincpowder, kanye ne-formaldehyde njengezinto zokusetshenziswa ukwenza ukusabela kwe-redox emanzini. Indlela yokusabela ithi:Na2S2O5+2Zn +2HCHO+5H2O=2NaHSO2.HCHO.2H2O +2ZnO

Ekuphenduleni kwe-redox, i-Na2S2O5 iyi-oxidant, i- #Zinc powder iyi-ejenti #reducing, futhi imikhiqizo yokusabela i-2NaHSO2.HCHO.2H2O ne-ZnO.

Ukuze kuthuthukiswe ukuqedwa kokusabela, kungaphazamisi ukuhlanzeka kwe-2NaHSO2.HCHO.2H2O, i-Zn powder eyengeziwe kanye ne-H2O izokwengezwa , njengoba i-HCHO izobangela ukungcola futhi ibeke engozini impilo yabaqhubi , ngakho-ke i-HCHO isekelwe kumbono wethiyori. inani.
