Hana ʻia ka puʻupuʻu #rongalite me ka hoʻohana ʻana i ka #sodiummetabisulfite, #zincpowder, a me formaldehyde ma ke ʻano he mea maka no ka hoʻokō ʻana i nā hopena redox i loko o ka wai. ʻO ke kumu hoʻohālikelike:Na2S2O5+2Zn +2HCHO+5H2O=2NaHSO2.HCHO.2H2O +2ZnO

I ka redox reaction, ʻo Na2S2O5 ka mea oxidant, ʻo #Zinc powder ka mea #reducing agent, a ʻo nā huahana hopena ʻo 2NaHSO2.HCHO.2H2O a me ZnO.

I mea e hoʻoikaika ai i ka pau ʻana o ka hopena, ʻaʻole e pili i ka maʻemaʻe o 2NaHSO2.HCHO.2H2O, e hoʻohui ʻia ka pauka Zn nui a me H2O, ʻoiai ʻo HCHO ka mea e hoʻohaumia ai a hoʻoweliweli i ke olakino o nā mea hoʻohana, no laila ua hoʻokumu ʻia ka HCHO ma ka theoretical. nui.


Kāhea iā mā˚ou

E hui pū me mākou a e lilo i mea mua e ʻike e pili ana i kā mākou huahana hou loa a me nā hoʻolaha.
