bir laba sulfide

Iron Two Sulfide: Tilmaame DhameystiranIron laba sulfide, oo sidoo kale loo yaqaan 'ferrous sulfide', waa iskudhis kiimiko ah oo leh qaacidada FeS. Hagahan waxa uu bixinayaa dulmar dhamaystiran oo ku saabsan sifooyinkiisa, isku dhafka, codsiyada, iyo tixgelinta badbaadada.

Astaamaha Iron Two Sulfide

Iron laba sulfide Waxay u jirtaa noocyo kala duwan oo crystalline ah, tan ugu caansan waa pyrrhotite macdanta dabiiciga ah. Macdantani waxay inta badan soo bandhigtaa ka kooban non-stoichiometric, taasoo la micno ah saamiga birta iyo baaruudku wax yar way kala duwanaan karaan. daahir bir laba sulfide waa cawl madow ilaa madow adag. Waa wax aan lagu milmi karin biyaha laakiin waxay la falgashaa asiidh si ay u soo saarto gaaska hydrogen sulfide, walax aad u sun ah oo guban karta. Meesha dhalaalkeedu waa mid aad u sarreeya, qiyaastii 1195 °C (2183 ° F).

Guryaha Kiimikada

Iron laba sulfide si sahal ah ula falgala acids, sida hydrochloric acid (HCl), si ay u soo saaraan gaaska hydrogen sulfide (H?S):FeS(s) +2HCl(aq) → FeCl?(aq) Dareen-celinta oksijiinta ayaa sidoo kale dhici karta, taasoo horseedaysa samaynta oksaydhyada birta iyo sulfur dioxide.

Synthesis of Iron Two Sulfide

Iron laba sulfide waxaa lagu soo saari karaa siyaabo dhowr ah. Habka caadiga ah waxaa ka mid ah in si toos ah looga falceliyo birta baaruudka heerkulka sare:Fe(s) + S(s) → FeS(s) Falcelintani waa mid aad u kacsan waxayna u baahan tahay kontorool taxadar leh si looga hortago kulaylka aan la xakameynin. Hab kale ayaa ku lug leh falcelinta roobka ee u dhexeeya birta milmisa (II) milix iyo milix sulfide milmi leh:FeCl?(aq) + Na?S(aq) bir laba sulfide Kaaso markaas la sifeyn karo oo la qalajin karo.

Codsiyada Iron Two Sulfide

Iron laba sulfide ka helo codsiyo warshado kala duwan. Mid ka mid ah codsiyada muhiimka ah ayaa ku jira soo saarista gaasta hydrogen sulfide, kaas oo loo isticmaalo hababka warshadaha kala duwan iyo sida reagent ee isku dhafka kiimikada. Waxa kale oo ay door ka ciyaartaa birta iyo birta, iyada oo u shaqeysa sida isha baaruudka. Intaa waxaa dheer, waa qayb ka mid ah midabada qaarkood. Si kastaba ha ahaatee, sababtoo ah sunta gaasaska ay soo saari karto, isticmaalkeedu wuxuu u baahan yahay taxadar badbaado oo muhiim ah.

Tixgelinta Badbaadada

Waa muhiim in wax laga qabto bir laba sulfide iyada oo taxadar leh ay sabab u tahay suurtagalnimada in ay la falgasho asiidh si ay u soo saarto gaaska hydrogen sulfide ee sunta ah. Qalabka ilaalinta shakhsi ahaaneed ee habboon (PPE), sida galoofyada, ilaalinta indhaha, iyo ilaalinta neefsashada, waa in had iyo jeer la isticmaalo marka la qabanayo xaruntan. Hawo ku filan ayaa lagama maarmaan ah si looga hortago ururinta gaasaska sunta ah. Haddii ay dhacdo soo-gaadhis, daryeel caafimaad oo degdeg ah waa in la raadsadaa.

Cilmi-baaris Dheeraad ah

Wixii macluumaad dheeraad ah oo faahfaahsan oo ku saabsan sifooyinka, synthesis, iyo codsiyada bir laba sulfide, la tasho suugaanta sayniska iyo xogta xogta sida kuwa uu bixiyo Machadka Heerarka iyo Tignoolajiyada Qaranka (NIST) https://www.nist.gov/. Xasuusnoow in hababka maaraynta badbaadada leh ay muhiim u yihiin markaad la shaqaynayso xaruntan kiimikada ah.
