Calcium Acetate ｜62-54-4
Tuairisgeul air bathar
Is e calcium acetate an salann calcium aig searbhag acetic. Tha am foirmle Ca(C2H3OO)2 aige. Is e calcium acetate an t-ainm àbhaisteach aige, agus is e calcium ethanoate an t-ainm eagarach IUPAC. Is e ainm nas sine acetate aoil. Tha an cruth anhydrous gu math hygroscopic; mar sin is e am monohydrate (Ca(CH3COO)2•H2O an cruth cumanta.
Ma thèid alcol a chur ri fuasgladh shàthaichte de calcium acetate, bidh gel semisolid, lasanta a’ cruthachadh a tha gu math coltach ri toraidhean “teas à tiona” leithid Sterno. Bidh tidsearan ceimigeachd gu tric ag ullachadh "California Snowballs", measgachadh de fhuasgladh calcium acetate agus ethanol. Tha dath geal air an gel a thig às, agus faodar a chruthachadh gus a bhith coltach ri ball-sneachda.
