Zinc Acetate Formula

Zinc Acetate Formula

Zinc is known to be a chemical element with symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and takes on a silvery gray appearance when oxidized, and is the first element in group 12 of the periodic table. Acetate is a compound of the formula C2H3O2-, also known as the acetate ion or monoacetic acid. It is a salt formed by combining acetic acid with alkaline, metallic, soil texture, non-metallic, or other bases.

Structure of Zinc acetate

Zinc coordinates the four oxygen atoms of acetic anhydride to form a tetrahedral environment. These tetrahedral polyhedra are linked by acetate ligands to form various polymeric structures. The zinc in Zinc Acetate Formula  dihydrate is octahedral, and both acetate groups are bidentate. 

Preparation of Zinc acetate

Reaction of Zinc and Acetate: When zinc reacts with acetate, zinc acetate is formed with the evolution of hydrogen gas. Here is the reaction:

Zn + CH3COOH ⇢ Zn(CH3COO)2 + H2

Reaction of Zinc Oxide and Acetic Acid: When zinc oxide reacts with acetic acid, it releases a water molecule to form zinc acetate. Here is the reaction:

ZnO + 2CH3COOH ⇢ Zn(CH3COO)2 + H2O

Properties Of Zinc Acetate Formula

Zinc Acetate Formula is a salt. Its chemical formula is Zn(CH3COO)2. Also written as zinc(II) acetate. Zinc Acetate Formula is commonly found in its dihydrate form, Zn(CH3COO)2.2H2O. Zinc acetate hydrates and anhydrous are commonly used as dietary supplements. Students are advised to visit Extramarks for all the formulas.

Zn(CH3COO)2 + 2NaOH → 2CH3COONa + Zn(OH)2

Thermal decomposition of zinc acetate: Thermal decomposition of zinc acetate under reduced pressure gives acetic anhydride and basic zinc acetate as products. Here’s the reaction:

2 Zn(CH3COO)2 → Zn4O(CH3COO)6 + (CH3CO)2O

Uses of zinc acetate

Zinc Acetate Formula is mainly used as a dietary supplement. Used as an adjunct in the treatment of colds.

It is also used to treat zinc deficiency in the body.

Zinc Acetate Formula is used to block copper absorption in the body in the treatment of Wilson’s disease. Given as an oral supplement.

It is used to treat acne topically in the form of lotions, ointments, or in combination with antibiotics. Zinc acetate is used in industry to preserve wood.

Sample Problems

Question 1: Discuss is the importance of zinc?

Zinc is a nutrient found throughout the body that supports immune system and metabolic function. Zinc is also important for wound healing and the development of taste and smell. The body usually gets enough zinc from a variety of foods. Poultry, lean meats, and fortified breakfast cereals are all healthy sources of zinc. 

Question 2: What are the uses of Zinc Acetate Formula ?

Zinc is essential for the growth and health of body tissues, so it is used to treat and prevent zinc deficiency. It is used in lozenges to treat the common cold. It is also used in many routine laboratory applications.

Question 3: How to write the chemical formula for zinc acetate? Resolution:

The chemical formula of zinc acetate is written using the Cross method. Zinc acetate contains zinc (Zn2+) and acetate (CH3COO–) radicals. Zinc is divalent and acetate is monovalent. When these valence members are crossed, the formula for zinc acetate is Zn (CH3COO)2.
