Ivyiza vy'umubiri

Sodium hydrosulfite ishirwa mu rwego rw’ikintu gishobora kwaka mu rwego rwa mbere, kikaba kizwi kandi kw’izina rya sodium dithionite. Igurishwa mu buryo bubiri: ifise amazi (Na2S2O4·2H2O) n’iyitagira amazi (Na2S2O4). Igishushanyo c’amazi kigaragara nk’ibisigazwa vy’umweru vyiza, mu gihe igishushanyo kitagira amazi ari ifu y’umuhondo ukeye. Ifise uburemere buringaniye bwa 2,3–2,4 kandi irabora iyo ifise ubushuhe butukura. Sodium hydrosulfite ishobora gusenyuka mu mazi akanye ariko ikabora mu mazi ashushe. Igisubizo caco c’amazi ntikigumaho kandi kigaragaza ubushobozi bukomeye bwo kugabanya, ivyo bikaba bituma kiba ikintu gikomeye co kugabanya.

Zana ibikoresho vyawe kugira ngo ushobore gushikana neza ifu y’ubwishingizi ivuye aho ikomoka, utababajwe n’uguhagarara kw’ugutanga. Fyonda hano kugira uronke amafaranga y’agaciro kanini n’ibikorwa vy’umugwi.
