Kev Muab Tso Los Ntawm Cov Fwj Reagent

Iav, yas; iav nres, roj hmab nres; qhov ncauj dav, nyias lub qhov ncauj; xim av, pob tshab; hauv av, tsis muaj av thiab lwm txoj kev faib tawm.

Hydrofluoric acid yuav tsum muab ntim rau hauv lub hwj yas, lwm yam reagents feem ntau siv iav fwj.

Alkaline tshuaj xws li sodium hydroxide thiab khob dej yuav tsum yog cov roj hmab plugs, tsis yog iav ntsaws. Rau cov kuab tshuaj organic xws li benzene, toluene, ether, thiab lwm yam, cov iav nres yuav tsum tsis txhob siv nrog cov roj hmab nres.

Lub raj mis lub qhov ncauj dav siv los tuav cov khoom sib zog, thiab lub raj mis qhov ncauj nqaim yog siv los tuav kua rov qab. Cov kua roj bromine yog muab cia rau hauv lub raj muaj caj dab-caj dab, dej ntxiv rau cov nplaim dej ua kom nws" dej ntim", thiab lub raj mis lub qhov ncauj tau ntim nrog siv quav ciab. Ib qho me me ntawm cov phosphorus dawb yuav tsum muab cia rau hauv dej.

Cov tshuaj tiv thaiv uas yooj yim rau xeb lossis paug thaum raug rau lub teeb feem ntau muaj nyob hauv cov hwj, xws li nitric acid, nitrate nyiaj, thiab dej chlorine. Khaws rau hauv qhov chaw txias thiab tsaus. Lwm cov fwj tsis muaj kob uas yog siv feem ntau.

Qhov av nres lub taub hau (sab hauv lub raj mis lub qhov ncauj yog khov tsim) tuaj yeem khaws lub foob thiab tiv thaiv qhov reagent los ntawm kev nqus cov dej noo thiab hloov kev tsim tawm. Lub raj mis nrog qhov poob hauv av yog hu ua poob dej. Reagents uas tau ua tsis zoo vim tias nqus tau cov pa roj carbon dioxide lossis dej vapor yuav tsum muab kaw thiab khaws cia (xws li NaOH, kua txiv qaub, tshuaj dawb tso, dej iav, Na2O2, thiab lwm yam). Concentrated hydrochloric acid, ammonia, iodine, benzene, toluene, ether thiab lwm cov organic uas muaj roj tsawg nyob hauv txhua lub raj mis muaj lub hau yas thiab ntim hauv qhov chaw txias thiab tsaus.

Ntawm cov reagents uas yooj yim kom tau oxidized thiab tsis meej, cov poov tshuaj nquag, sodium, calcium, thiab lwm yam yog khaws cia hauv roj av; potassium iodide, ferrous sulfide, sodium sulfate thiab lwm cov khib nyiab feem ntau yog khaws cia yam tsis tau khaws cia cov tshuaj; thaum siv cov tshuaj ferrous sulfate lossis ferrous oxide tov Muab me me ntawm cov hmoov hlau lossis hlau rau tes.

Feem ntau cov chaw soj nstuam thoob plaws ntiaj teb siv cov fwj dej ntim tshuaj uas tsim los ntawm cov tuam txhab German vim tias lawv lub hau yog ua cov yas xiav, tseem hu ua xiav-cap reagent fwj.
