Calcium Acetate 62-54-4
Khoom Description
Calcium Acetate yog calcium ntsev ntawm acetic acid. Nws muaj cov qauv Ca (C2H3OO) 2. Nws lub npe qauv yog calcium acetate, thaum calcium ethanoate yog lub npe IUPAC systematic. Lub npe laus yog acetate ntawm txiv qaub. Daim ntawv anhydrous yog hygroscopic heev; yog li ntawd cov monohydrate (Ca(CH3COO)2•H2O yog hom ntawv.
Yog hais tias ib qho cawv ntxiv rau cov tshuaj saturated calcium acetate, semisolid, flammable gel cov ntaub ntawv uas zoo li "cov kaus poom kub" cov khoom xws li Sterno. Chemistry cov kws qhia ntawv feem ntau npaj "California Snowballs", sib tov ntawm calcium acetate tov thiab ethanol. Cov txiaj ntsig gel yog xim dawb, thiab tuaj yeem tsim kom zoo li lub pob zeb.
