Kev siv thiab kev ceev faj ntawm kev lag luam potassium nitrate

Muaj cov poov tshuaj nitrate yog ib yam khoom tsis muaj zog, feem ntau hu ua hluav taws nitrate lossis av nitrate. KNO3 yog hais txog nitrate ntawm poov tshuaj. Nws yog xim tsis muaj xim thiab pob tshab orthorhombic crystals lossis rhombic muaju lossis hmoov dawb, tsis muaj ntxhiab, tsis muaj tshuaj lom, qab ntsev thiab ua kom zoo dua. Nws absorbs me ntsis noo noo nyob rau hauv cov huab cua, tsis yooj yim rau agglomerate, yog yooj yim soluble nyob rau hauv dej, yuav yaj nyob rau hauv kua ammonia thiab glycerol, thiab yog insoluble nyob rau hauv kiag li ethanol thiab ether.
Kev ceev faj rau kev ua haujlwm muaj cov poov tshuaj nitrate: Kaw qhov kev ua haujlwm thiab ntxiv dag zog rau qhov cua. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug nquahu kom cov neeg ua haujlwm hnav hood-hom hluav taws xob cua tshuab lim cov plua plav pov thawj ua pa, polyethylene tiv thaiv kab mob, thiab hnab looj tes neoprene. Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Kev haus luam yeeb yog txwv tsis pub nyob hauv chaw ua haujlwm.
Khaws kom deb ntawm cov khoom siv hluav taws xob thiab hluav taws kub. Zam kev tsim plua plav. Tsis txhob sib cuag nrog cov tshuaj txo cov kua qaub, thiab cov hmoov hlau ua haujlwm. Thaum tuav, thauj khoom thiab tshem tawm nrog kev saib xyuas kom tsis txhob muaj kev puas tsuaj rau cov ntim thiab ntim. Nruab nrog cov khoom sib xws thiab ntau ntawm cov khoom siv tua hluav taws thiab cov khoom siv kho mob thaum muaj xwm ceev. Cov thawv khoob yuav ua rau muaj teeb meem seem.
