1.Sodium acetate kuma aka sani da sodium acetate.Mara launi, mara wari, crystal columnar monoclinic bayyananne, ko fari crystalline foda.
2.A cikin samar da abinci, ana amfani da shi azaman buffer don kayan yaji da kuma kayan abinci na nama.Sarrafa abin da ya faru mai danko da fungi ke haifarwa a cikin samar da burodi da amfani da shi a cikin adana hatsi tare da babban abun ciki na ruwa;Hakanan za'a iya amfani da wannan samfurin azaman kayan aikin rini na littafin sinadarai (mordant), buffer don masana'antar hoto, reagent sinadarai da matsakaicin magunguna;Hakanan za'a iya amfani da shi azaman albarkatun ƙasa don haɗa samfuran sinadarai, kamar furan acrylic acid, acetate esters, chloroacetic acid, acetic anhydride da cinnamic acid.
3.Colorless da wari crystal, wanda za a iya weathered da combustible a cikin iska.Mai narkewa a cikin ruwa da ether, dan kadan mai narkewa a cikin ethanol.Matsakaicin narkewar sodium acetate trihydrate shine 58 ℃, ƙarancin dangi shine littafin sinadarai1.45, kuma madaidaicin konewar kwatsam shine 607.2 ℃.Cire kwayoyin ruwa 3 a 123 ℃.Matsakaicin narkewar anhydrous sodium acetate shine 324 ℃, kuma girman dangi shine 1.528.
