Description
Zinc hydroxide, with the chemical formula Zn(OH)2, is a white solid that typically forms in solution. It is an amphoteric compound, meaning it can react with both acids and bases. Zinc hydroxide is not very stable as a dried solid, and thus, a standard form of it is not commercially available. It occurs naturally as the rare minerals Wulfingite, Ashoverite, and Sweetite. Physically, it is characterized by its colorless orthorhombic crystals, a density of 3.053 g/cm3, and it decomposes at 125°C. It is slightly soluble in water and almost insoluble in water, forming both zinc salts and zincates when dissolved.
Uses
Used in Chemical Industry:
Zinc hydroxide is used as an intermediate in the chemical industry for the production of various zinc compounds, such as zinc oxide and zinc salts.
Used in Surgical Dressings:
In the medical field, zinc hydroxide is used as an absorbent in surgical dressings due to its ability to absorb biological fluids and promote healing.
Used in Rubber Compounding:
Zinc hydroxide is also utilized in the rubber industry as a compounding agent, which helps improve the properties of rubber products, such as their strength, flexibility, and durability.
Preparation
The compound is prepared by adding a strong alkali to a solution of zinc sulfate or chloride: ZnSO4 + 2NaOH → Zn(OH)2 + Na2SO4.
Check Digit Verification of cas no
The CAS Registry Mumber 20427-58-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,2 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20427-58:
(7*2)+(6*0)+(5*4)+(4*2)+(3*7)+(2*5)+(1*8)=81
81 % 10 = 1
So 20427-58-1 is a valid CAS Registry Number.
