Aikace-aikace:
1. Amfani da sodium hydrosulfite yana da faɗi sosai, galibi ya haɗa da rage rini, rage tsaftacewa, bugu da canza launi a cikin masana'antar yadi, da bleaching na siliki, ulu, nailan da sauran yadudduka. Tunda sodium hydrosulfite ba ya ƙunshe da ƙarfe mai nauyi, launi na masana'anta mai bleaked yana da haske sosai kuma ba shi da sauƙin fashewa.

2. Sodium hydrosulfite kuma za a iya amfani da su wajen wanke abinci, kamar su gelatin, sucrose, candied fruit, da dai sauransu, da sabulu, dabba ( shuka) mai, bamboo, ain yumbu bleaching.

3. A fannin hada kwayoyin halitta, ana amfani da sodium hydrosulfite a matsayin wakili mai ragewa ko mai yin bleaching wajen samar da rini da magunguna, musamman a matsayin wakili na bleaching don yin takarda na itace.

Mai ƙonewa:Sodium dithionite abu ne mai ƙonewa ajin farko idan aka jika bisa ga ƙa'idodin ƙasa. Zai mayar da martani da ƙarfi idan ya haɗu da ruwa, yana samar da iskar gas mai ƙonewa kamar hydrogen sulfide da sulfur dioxide, kuma yana fitar da adadi mai yawa na zafi. Ma'aunin amsawa shine: 2Na2S2O4+2H2O+O2=4NaHSO3, kuma samfuran sun kara mayar da martani don samar da hydrogen sulfide da sulfur dioxide. Sodium dithionite yana da matsakaicin valence yanayin sulfur, kuma abubuwan sinadarai ba su da tabbas. Yana nuna ƙarfi rage kaddarorin. Lokacin da ta ci karo da acid mai ƙarfi mai ƙarfi, irin su sulfuric acid, perchloric acid, nitric acid, phosphoric acid da sauran acid mai ƙarfi, su biyun za su fuskanci redox reaction, kuma halayen yana da tashin hankali, yana sakin babban adadin zafi da abubuwa masu guba. Ma'aunin amsawa shine: 2Na2S2O4+4HCl=2H2S2O4+4NaCl

Konewar kai tsaye:Sodium dithionite yana da wurin konewa kai tsaye na 250 ℃. Saboda ƙarancin wutan sa, yana da ƙarfi mai ƙarfi na aji na farko (madaidaicin wutar lantarki gabaɗaya yana ƙasa da 300 ℃, kuma madaidaicin walƙiya na ƙarancin narkewa yana ƙasa da 100 ℃). Yana da sauƙin ƙonewa lokacin da aka fallasa ga zafi, wuta, gogayya da tasiri. Gudun konewa yana da sauri kuma haɗarin wuta yana da yawa. Gas hydrogen sulfide gas da aka samar yayin aikin konewa na iya haifar da wurin konewa mafi girma, yana ƙara haɗarin wuta.

Fashewa:Sodium dithionite abu ne mai launin rawaya mai haske. Abun foda yana da sauƙi don samar da cakuda mai fashewa a cikin iska. Fashewar kura yana faruwa a lokacin da aka ci karo da tushen wuta. Cakudar sodium dithionite da mafi yawan oxidants, irin su chlorates, nitrates, perchlorates, ko permanganates, abu ne mai fashewa. Ko da a gaban ruwa, yana fashewa ne bayan wani ɗan rikici ko tasiri, musamman bayan bazuwar zafin jiki, iskar gas mai ƙonewa da ke haifarwa bayan abin da ya faru ya kai iyakar fashewa, to haɗarin fashewa ya fi girma.
