Biraha alkali

Biraha alkali - francium, cesium, rubidium, potassium, sodium, lithium - si yeedhay sababtoo ah xaqiiqda ah in qaab alkali by reaction biyo. Sababo la xiriira awoodda sare si ay fal walxahaasi waa in lagu kaydiyaa hoos lakabka ah ee saliidda macdanta ama la shito. The ugu firfircoon xeryahooda, kuwaas waxaa loo arkaa francium (tahay shucaac).

Biraha alkali - walxaha jilicsan, midabka silvery. Waxa ay dusha immika jaray ayaa luster sifo. Biraha alkali waxaa dhalaalay iyo isku kari at kul hoose, waxay leeyihiin conductivity kaamerada iyo korontada sare. Waxay sidoo kale leeyihiin cufnaanta hooseeyo.

guryaha Chemical biraha alkali

Muqaadaraadka yihiin wakiilada yaraynta xoog, xeryahooda ku muujiyaan degree ah lagu qayilo (gaar) +1. Iyada oo korodhka miisaanka Biraha alkali qaaradda iyo kordhay yaraynta awoodda. Ku dhowaad dhammaan xeryahooda ku milma biyo yihiin, oo iyagu waa Madbacada qaranka ee dabiiciga ah.

Iyada oo kululaynta dhexdhexaad Biraha alkali shidid hawada. In lala hydrogen ku sameeyaan hydrides walax cusbo-sida. waxyaabaha sari caadi ahaan waa peroxides.

oxides biraha alkali jira cunnooyinka adkaha ah huruud ah (oxides of rubidium iyo potassium), cad (oxides ah sodium iyo lithium) iyo (xabagta Cesium) orange midabada. oxides Kuwani waa awood ficil biyo, acids, oxygen, acid iyo oxides amphoteric. Kuwani astaamaha asaasiga yihiin asalka ah oo dhan oo iyaga ka mid oo ay leeyihiin dabeecad fahmayaan.

peroxides biraha alkali - budada midab huruud ah-cad. Waxay awood u of ficil la carbon dioxide iyo gaasaska carbon monoxide, acids, nonmetals, biyo.

hydroxides biraha alkali waa L. biyo, cunnooyinka adkaha cad. In xeryahooda, kuwaas waxaa lagu muujiyey guryaha aasaasiga ah (dhalaalaya ku filan) alkalis. saldhigyadii Lithium in ciidamada Franz iyo degree of milmi biyo kordhay. Hydroxides tixgeliyo electrolytes ku filan oo xoog leh. Waxay fal la cusbada, hydroxides amphoteric iyo oxides, qaar non-birta, oxides acid. Marka laga reebo xarunta inteeda kale lithium muujiyaan xasilooni kaamerada. Calcining hydroxide lithium waa ay kala daatay biyo iyo xabagta ku. Ayaa sheegay in xeryahooda waxaa laga heli by hab electrolysis of xal chloride aqueous of tiro ka mid ah cadaanyo dheefshiidka. Hydroxides sidoo kale diyaarisay by qaybaha ficil (ama oxides) iyo biyo.

Ku dhawaad oo dhan Biraha cusbada ku tilmaamay (marka laga reebo qaar cusbada lithium) waa L. biyo si fiican. Waxa asaasay by acids daciif ah, xal saline leeyihiin dhexdhexaad dareen-celin (xumadoodu) ay sabab u tahay hydrolysis oo cusbo ku sameeyay acids sida xoogga leh aan hydrolyzed. cusbada Common waa dhagax (sodium) cusbo, xabag ah silicate (galaas oo biyo ah), amooniyam potassium, cusbo bertoletova, -KP, soda dhalada, ash soodhaha, iyo kuwa kale.

All xeryahooda alkali awood u leeyihiin in la beddelo midabka ololka. Waxa loo isticmaalaa in falanqayn kiimikada. Sayidka, Carmine olol Cas wasakheeyey udhigo lithium, in buluug - udhigo potassium ee jaalaha ah - sodium pink anfac - rubidium, buluug-cas - cesium.

Sababo la xaqiiqada ah in dhammaan unugyada xumadoodu waa wakiilada yaraynta ugu awooda badan, waxay heli karaan cusbada shubay by electrolysis.

Isticmaalka biraha alkali

xubno ka waxaa loo isticmaalaa in dhinacyo kala duwan ee jimicsiga aadanaha. Tusaale ahaan, cesium waxaa loo isticmaalaa in unugyada photoelectric. daawaha dhalista waxaa loo isticmaalaa sida lithium Hannaan. Sodium waxa ay joogtaa laambadihii gaas-dheecaanku ka daadanayo, tigoodu nuclear sida coolant ah. hawlaha cilmi waxaa loo isticmaalaa rubidium.
