No. It is ionic compound.
Sulfur and Oxygen are both non-metals so their chemical bond is a covalent one.
Covalent
The acetate groups are comprised of covalent bonds, but they are ionically bonded with the calcium.
Is zinc a metal? Yes? Then, no, it's not covalent.
Vinegar is a mixture not a compound. The main constituent, apart from water, is acetic acid (ethanoic acid), CH3COOH. This is molecular is a weak acid and dissociates in water to form acetate ion and H+
Lithium acetate (CH3COOLi) is an ionic compound.
The name of the compound Zn C2H3O22 or Zn (CH3COO)2 is Zinc acetate.
Zinc generally makes covalent bonds with non-metals. Organometallic zinc compounds like dimethyl zinc or diethyl zinc are covalent.
Zinc sulfide is a covalent compound.
sodium acetate and zinc phosphate
zinc acetate is white in colour.
of course it is ionic what else could it be?
Yes, it contains both. The sodium forms an ionic bond with the one oxygen with a single bond (not double) with the carbon, becoming the cation (positive charge). This oxygen and all other atoms in the acetate form covalent bonds.
Sulfur and Oxygen are both non-metals so their chemical bond is a covalent one.
Covalent
The acetate groups are comprised of covalent bonds, but they are ionically bonded with the calcium.
