I-ejenti yokunciphisa: I-Sodium Hydrosulfite
Ibizo lekhemikhali: I-sodium dithionite.
Nayimadaniswa nama-ejenti we-oksijini, i-sodium hydrosulfite ibangela umonakalo omncani khulu eentjhini. Ingasetjenziswa eentjhini ezenziwe ngemicu ehlukileko ngaphandle kokubanga umonakalo, kungebangelo ibizo elithi "hydrosulfite" (okutjho ukuphepha kwayo). Yinto yamakhemikhali emhlophe enesihlabathi nofana ipuyere ephuzi ekhanyako. Ibola ku-300°C (ivutha ku-250°C), ayincibiliki ku-ethanol, incibilika ku-sodium hydroxide solution, begodu isabelana ngamandla namanzi, okwenza ukutjhisa.
Ukulawulwa kwekhwalithi ye-sodium sulfite kwethu kuqinile khulu, lapho iqoqo ngalinye lizihlolela khona efemini. Tlika lapha ukuthola iingcaphuno ezisezingeni eliphezulu.
