Silver sulphate, amadziwikanso kutiAg2SO4, ndi gulu lomwe limagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndi kafukufuku. Komabe, monga mmene zimakhalira ndi mankhwala alionse, m’pofunika kusamala kwambiri ndi mankhwalawo komanso kumvetsa kuopsa kwake. M'nkhaniyi, tiwona ngatisiliva sulphatendi zovulaza ndikukambirana za kagwiritsidwe ntchito kake, katundu, ndi njira zodzitetezera.
Choyamba, tiyeni timvetsetse katundu wasiliva sulphate. Ndi crystalline yoyera yolimba, yopanda fungo komanso yosasungunuka m'madzi. The Chemical formulaAg2SO4zimasonyeza kuti wapangidwa awiri siliva (Ag) ayoni ndi mmodzi sulphate (SO4) ion. Nthawi zambiri amapangidwa ndi anachitasiliva nitratendi mankhwala a sulphate. Unyinji wa molar wasiliva sulphatepafupifupi 311.8 g/mol, ndipo nambala yake ya CAS (Chemical Abstracts Service) ndi10294-26-5.
Silver sulphateali ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana. Imodzi mwa ntchito zake zazikulu ndi mu chemistry laboratories monga reagent pa synthesis wa mankhwala ena. Amagwiritsidwanso ntchito popanga zopangira siliva zomwe zimagwiritsidwa ntchito popanga zinthu zosiyanasiyana zachilengedwe. Kuonjezera apo,silver sulphate is amagwiritsidwa ntchito m'makampani opanga ma electroplating kuti azivala zinthu ndi siliva woonda. Kuchita zimenezi kumawonjezera kukongola kwa zinthu zosiyanasiyana monga zodzikongoletsera, zodzikongoletsera, ndi zinthu zokongoletsera.
Tsopano, tiyeni tikambirane funso ngatisiliva sulphatendi zovulaza.Silver sulphatezimabweretsa ziwopsezo ku thanzi la munthu ndi chilengedwe ngati sizikugwiridwa kapena kugwiritsidwa ntchito molakwika. Amawonedwa ngati poizoni ngati atalowetsedwa, atakowetsedwa, kapena akhudzana ndi khungu kapena maso. Kuwonekera kwa nthawi yaitali kapena mobwerezabwereza pamaguluwa kungayambitse mavuto osiyanasiyana a thanzi, monga kupsa mtima kwa maso, khungu la khungu, vuto la kupuma, ndi kuwonongeka kwa chiwalo chamkati.
Monga momwe zilili ndi chinthu chilichonse chowopsa, ndikofunikira kusamala mukamagwira ntchitosiliva sulphate. Kapangidwe kameneka kamayenera kugwiridwa nthawi zonse pamalo abwino mpweya wabwino, makamaka pansi pa fume hood, kuchepetsa chiopsezo chokoka mpweya. Zida zodzitetezera, kuphatikizapo magolovesi, magalasi, ndi malaya a labu, ziyenera kuvalidwa kuti musayang'ane khungu ndi maso. Ngati mwapezeka mwangozi, pitani kuchipatala mwamsanga.
Posunga,siliva sulphateziyenera kusungidwa muzotengera zotchinga mpweya kutali ndi kutentha, malawi ndi zinthu zosagwirizana. Zisungidwe pamalo ozizira, ouma komanso kutali ndi dzuwa. Ndikofunikiranso kutsatira njira zoyenera zotayirasiliva sulphatendi zinyalala zilizonse zomwe zimachokera ku ntchito yake. Malamulo am'deralo ndi malangizo okhudza kutaya kwa mankhwala owopsa akuyenera kutsatiridwa mosamalitsa kuonetsetsa chitetezo cha chilengedwe ndi zamoyo.
Pomaliza, ngakhalesiliva sulphatechimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, chingakhaledi chowopsa ngati sichikugwiridwa bwino kapena kugwiritsidwa ntchito molakwika. Ndikofunikira kumvetsetsa mawonekedwe ake ndi zoopsa zomwe zingagwirizane nazo.Silver sulphateangagwiritsidwe ntchito mosamala ndi mosamala m'machitidwe osiyanasiyana potengera njira zoyenera zotetezera, monga kuvala zida zodzitetezera ndikutsatira njira zoyenera zosungira ndi kutaya, pochepetsa zoopsa zomwe zingatheke.
