Bromine ruwa - da ruwa-ruwa bayani na bromine

Bromine ruwa ne diluted da ruwa bromo. Its a lissafai dauki mafi yawa ana rubuta ta a kalma guda - Br2, ko da yake yana a cikin bayani a cakuda biyu acid - HBrO (hypobromous acid) da kuma HBr (hydrobromic acid). Wannan fili yana da wani yellow-orange launi da kuma a gwada low sanyinsu. Yana da wani karfi oxidant wanda yake iya karkashin alkaline yanayi zuwa oxidize cations irin karafa - Cr ^+3, mn ^+3, Fe ^+2, Co ^{₊ 2,} Ni ^+3. Bugu da kari na Br ₂ rage PH darajar (PH), saboda bromine ruwa ya ƙunshi free acid.

Wannan chemically aiki abu, wanda zai iya amsa tare da biyu inorganic da kwayoyin abubuwa. Ka yi la'akari da wasu sunadarai matakai da aka fili.

Discoloration bromine ruwa na samar da ingantaccen dauki duk unsaturated hydrocarbons. Domin gudanar da wannan gwaji na bukatar a kananan adadin wani alkene ko alkyne gauraye a wani gwajin bututu da ₂ Br. A lokacin wannan dauki Bugu da kari na bromine kwayoyin halitta a wurin katsewa biyu ko sau uku bond. The bacewar na yellow-orange launi a cikin wannan dauki wani hujja dauka unsaturation hydrocarbon.

A sinadaran dauki "phenol - bromine ruwa" da ake amfani da precipitate daga bayani bromo mahadi. Idan hulda da abubuwa da za'ayi a karkashin anhydrous yanayi, da samuwar tribromophenol zai dauki kamar wata kwana. Saboda haka, kamar yadda mai kara kuzari, a kananan adadin H ₂ O.

Bromine ruwa a dakin gwaje-gwaje shirya kamar haka: 1 ml na bromine aka kara 250 ml na distilled ruwa, da jujjuyawa maida. A shirye bayani da aka adana a wani tam rufaffiyar kwantena na duhu gilashi. Idan shirya Br ₂ adana a cikin haske ko haske a cikin flask, da oxygen juyin halitta zai faru ne saboda abun ciki na hypobromous acid. Aiki a kan shirye-shiryen da reagent ne da za'ayi a cikin wani fume kaho. Tun da bromine kanta ne m, kuma shi ya ƙunshi bromine ruwa, shi wajibi ne don yi taka tsantsan a lokacin da yin aiki tare da shi.

Wajibi ne a yi la'akari da cewa a lamba tare da Br ₂ ga fata bayyana sosai itchy, da kuma tsawo daukan hotuna iya sa ulcers. Idan abu ya shiga cikin fata, ya kamata a wanke da ruwa, sa'an nan sodium carbonate. Lokacin da wani babban rauni surface ko zurfin fata raunuka epidermis bugu da žari smeared da maganin shafawa, wanda ya hada da NaHCO _3.

Bromine ruwa ne yadu a yi amfani da sinadaran bincike da kuma kira na Organic kayayyakin. Saboda haka, ta yin amfani da a samar da bromine-dauke da kwayoyi. Kuma a nan shi ne dole ya zama m, saboda su yi tsawo amfani iya kai ga cuta - bromism. Babban bayyanar cututtuka - lethargy, gajiya, fata na gaggawa. Domin sauri kau na bromine ions daga jiki dieting da high gishiri ciki da yalwa da abin sha. More bromine ruwa da ake amfani a tsaka-tsaki matakai na samar da retardants - abubuwa da kare kwayoyin fili na ignitions. Su impregnated yadudduka, itace, kayan gini.
