Mix ruwan birki da bleach. Me zai faru?
Abun da aka haɗa da reagents
Ruwan birki ya ƙunshi polyglycols - nau'ikan polymeric na polyhydric alcohols (ethylene glycol da propylene glycol), boric acid polyesters da masu gyara. Chlorine ya hada da hypochlorite, hydroxide da calcium chloride. Babban reagent a cikin ruwan birki shine polyethylene glycol, kuma a cikin Bleach - hypochlorite. Hakanan akwai nau'in ruwa na samfuran gida mai ɗauke da chlorine, wanda sodium hypochlorite ke aiki azaman wakili na oxidizing.
Bayanin tsari
Idan kun haxa ruwan bleach da ruwan birki, za ku iya ganin wani mummunan dauki tare da fitar da iskar gas mai yawa. Sadarwar ba ta faruwa nan da nan, amma bayan 30-45 seconds. Bayan samuwar geyser, samfuran gas suna ƙonewa, wanda sau da yawa ya ƙare a fashewa.
Ba a ba da shawarar yin gwajin a gida ba. Don hanyar, yakamata a yi amfani da kayan kariya, kuma yakamata a aiwatar da martani a cikin hurumin hayaki ko a cikin sarari a sarari mai nisa.
tsarin amsawa
A cikin gwajin, ana amfani da bleach da aka shirya. Maimakon bleach, zaka iya amfani da sodium hypochlorite, wanda ya ƙunshi har zuwa 95% chlorine mai aiki. A farkon, da hypochlorite gishiri bazuwa tare da samuwar atomic chlorine:
NaOCl → NaO+ + CI-
Sakamakon sinadarin chloride ion yana bombards da kwayoyin ethylene glycol (polyethylene glycol), wanda ke haifar da rushewar tsarin polymer da sake rarraba yawan electron. A sakamakon haka, monomer, formaldehyde, ya rabu da sarkar polymer. Kwayoyin ethylene glycol an juyar da su zuwa radical electrophilic, wanda ke amsawa da wani ion chloride. A mataki na gaba, an raba acetaldehyde daga polymer, kuma a ƙarshe mafi sauƙi alkene, ethylene, ya kasance. Babban tsarin rushewa shine kamar haka:
Polyethylene glycol ⇒ formaldehyde; Acetaldehyde; Ethylene
Rushewar lalatawar ethylene glycol a ƙarƙashin aikin chlorine yana tare da sakin zafi. Koyaya, ethylene da formaldehyde sune iskar gas mai ƙonewa. Don haka, a sakamakon dumama cakudawar amsawa, samfuran gas suna ƙonewa. Idan yawan abin da ya faru ya yi sauri sosai, fashewa yana faruwa saboda bazuwar gaurayawan ruwan gas na kwatsam.
Me yasa martanin baya faruwa?
Sau da yawa lokacin hada ruwan birki da bleach, ba a ganin komai. Wannan yana faruwa saboda dalilai masu zuwa:
- An yi amfani da tsohuwar bleach na gida
Lokacin adanawa a waje, calcium hypochlorite sannu a hankali yana raguwa zuwa calcium carbonate da calcium chloride. Abubuwan da ke cikin chlorine mai aiki an rage zuwa 5%.
- Temperatureananan zafin jiki
Don ci gaba da amsawa, ya zama dole don dumama ruwan birki zuwa zazzabi na 30-40 ° C
- Bai isa ba lokaci ya wuce
Halin sarkar mai tsattsauran ra'ayi yana faruwa tare da karuwa a hankali a cikin sauri. Zai ɗauki kimanin minti 1 kafin canje-canje na gani su bayyana.
Yanzu kun san abin da zai faru idan bleach ya haɗu da ruwan birki da yadda hulɗar ke faruwa.
