Sodium sulphide

Emanzini yi sodium (sodium sulphide zobugcisa) yikhompawundi apho sisetyenziswa ngokubanzi kushishino. Ngenxa yoko, le nto isetyenziswa yokunyibilikisa isinyithi, imichiza, ishishini ukukhanya kunye namanye amashishini. Sodium sulphide, ingakumbi, ezisetyenziswa xa kusenziwa yintlama, idayi, ekusetyenzweni ngesikhumba. Iziyobisi isetyenziswa ukunyibilika ezinye iintsimbi non-ayoni. Sodium emanzini buyafuneka kummandla chemistry yohlalutyo. Oku kusetyenziswa reagent kwiinkqubo ezahlukeneyo.

Sodium sulphide. Formula (Na2S)

I eliqhelekileyo karhulumente emzimbeni zenkqunto kuthathwa ubunzima bomzi, apho phezulu-onovakalelo, okanye crystals hygroscopic. Le into yenziwa ngohlobo litye lesikhumbuzo amaxabiso 3 kwifom kwamaqondo eparticulate (ngokohlobo kukubola okanye granules). Faka ukuba imveliso ukuba ukukhanya-mdaka, lisuke labuna umbala otyheli okanye nombala. Ngaphezulu kakhulu okanye nawuphi na umbala ibonisa arhente igcwala ebalulekileyo. Ezo emanzini sodium yaye ulahlekelwa iipropati luncedo ukuba angakulungeli ukusetyenziswa practical. Imveliso Injongo zobugcisa iqulathe ukusuka amathandathu amathathu namashumi amathandathu anesixhenxe ekhulwini izinto isiseko phantsi komqathango wokuba le iqhezu ubunzima intsalela ezingenakunyibilika alikho ngaphezu kwesiqingatha ekhulwini.

Ukungqinelana ukuhlelwa inqanaba engozini Isiqalelo setyuwa yabantu kabi wabelwa ukuba iklasi yesibini. Le nto ke lula kwaye Uyadubula. Kule meko, oko Kukhethwa ukugcina imathiriyeli kumagumbi ezivaliweyo ukuba baxhotyiswe zonke izibonelelo ezidingekayo ukuqinisekisa ukhuseleko emlilweni. Ayikhuthazwa ukususa iphakheji imveliso de isicelo ngqo kweziyobisi. Ngoxa ukugcina ingqibelelo izikhongozeli sodium emanzini kunokugcinwa iminyaka emibini. Term ekusetyenzisweni ngempumelelo kule meko kuphela konyaka.

Ukuthutha imveliso kufuneka kwenziwa naziphi na iindlela zezithuthi iinqwelo okanye izingxobo ezivaliweyo. ingqalelo Kuninzi kufuneka ihlawulwe ukukhweliswa ukothula eziphathekayo, ingakumbi xa izakuthatwa qhagamshelana ngqo kunye nemveliso, zahlanganiswa kwimigqomo bhetyebhetye. Ngexesha zokuhamba ukuphepha ukugcina okwexeshana kwiindawo ezivulekileyo okanye zokugcina, kakuhle bekwazi ukwenza oku.

Technical sodium emanzini yemveliso yaseTshayina igcwele ezingxoweni ezikhethekileyo emashumi mabini anantlanu eekhilogram. Packaging inikeza ukukhuselwa igcwala ngaphambi nokuqhelana ukukhanya. Ngaphezulu, njengokuba yempazamo ekupakishweni imigqomo yentsimbi zisetyenziswa kuphela imveliso yemichiza, izikhongozeli (CK-1-5 (7)), okanye izikhongozeli sithambile ukusetyenziswa elinye. Le nto kufakwa ezingxoweni amaphepha (iPIN okanye ezintlanu-umaleko) kunye nqanawa engaphakathi - bag polyethylene. Izingxobo isenokuba ubunzima net ayikho kilograms ngaphezu amahlanu.

Zipakishwe izikhongozeli ezizodwa kweziyobisi ithuthelwe i kaloliwe uhlobo evulekileyo.

Product konga 1,856 gram nganye sentimitha cc. Ukunyibilika lobushushu kufika kumgomo we 1180. Le imveliso hygroscopic kakhulu. Xa amanzi ashushu amabini zichithakala 13.6% ngo-97,5 degrees - 45% ye eziphathekayo. Le mveliso iyakwazi yokutshata carbohydrate crystalline. Kuba izisombululo zolwelo sodium emanzini zobugcisa iimpawu obrak reaction.

Le haydrolisis lwenziwa sulphide sodium kwakunye iityuwa ezithi ayila asidi kunye nesiseko esomeleleyo. Phenolphtalein kwityhubhu uvavanyo kunye nesisombululo uba epinki. Oku kubonisa ukuba medium-alkali ze senziwa ityhubhu yovavanyo. Ngenxa yoko, sodium emanzini, kwakunye nezinye iityuwa ezithi ayila asidi kwaye kwisiseko esiluqilima, hydrolysed ukwenza ngenxa kwealkali.
