I-Calcium Acetate: 62-54-4
IiNkcazo zeeMveliso
I-Calcium Acetate yityuwa ye-calcium ye-acetic acid. Inefomula ethi Ca(C2H3OO)2. Igama layo eliqhelekileyo yi-calcium acetate, ngelixa i-calcium ethanoate ligama le-IUPAC elicwangcisiweyo. Igama elidala yiacetate yekalika. Ifom ye-anhydrous i-hygroscopic kakhulu; ngoko ke imonohydrate (Ca(CH3COO)2•H2O yindlela eqhelekileyo.
Ukuba utywala bongezwa kwisisombululo esigcweleyo se-calcium acetate, i-semisolid, iifom zejeli ezinokutsha ezifana neemveliso "zokushisa okusemathinini" ezifana ne-Sterno. Abafundisi beKhemistri bahlala belungiselela "i-California Snowballs", umxube wesisombululo se-calcium acetate kunye ne-ethanol. Ijeli ephumayo inombala omhlophe, kwaye inokubunjwa ukuze ifane nebhola leqhwa.
