Bundu re#rongalite rinogadzirwa nekushandisa #sodiummetabisulfite, #zincpowder, uye formaldehyde semidziyo yekuitisa redox reaction mumvura. The reaction formula is:Na2S2O5+2Zn +2HCHO+5H2O=2NaHSO2.HCHO.2H2O +2ZnO

Mune redox reaction, Na2S2O5 ndiyo oxidant, #Zinc powder ndiyo #reducing agent, uye maitiro ekugadzirisa ndeye 2NaHSO2.HCHO.2H2O uye ZnO.

Kuti usimudzire kupedzwa kwekuita, kusakanganisa kuchena kwe2NaHSO2.HCHO.2H2O, yakawandisa Zn powder uye H2O ichawedzerwa , sezvo HCHO inokonzera kusvibiswa uye kuisa pangozi hutano hwevashandi, saka HCHO inobva pane zvinyorwa. mari.


Taura nesu

Joinha isu uye uve wekutanga kuziva nezve edu azvino zvigadzirwa uye kukurudzira.
