Description
Gold hydroxide, also known as auric hydroxide, is a chemical compound with the formula Au(OH)3. It is a brown powder that decomposes at 100°C and is insoluble in water but soluble in acid. Gold hydroxide is a solid with unique chemical properties that make it suitable for various applications.
Uses
Used in Gold-Plating Solutions:
Gold hydroxide is used as a key component in gold-plating solutions for its ability to provide a thin, even layer of gold on various surfaces. This application is particularly useful in the electronics industry for creating conductive pathways and in the jewelry industry for adding a layer of gold to enhance the appearance and value of the item.
Used in Decorating Porcelains:
In the ceramics industry, gold hydroxide is used as a decorative agent for porcelains. Its unique properties allow for the creation of intricate designs and patterns on porcelain items, adding a touch of luxury and elegance.
Used in Synthesis of Gold Hydroxide Complexes:
Gold hydroxide is used as a starting material for the synthesis of gold hydroxide complexes with N-heterocyclic carbene. These complexes have potential applications in various fields, including catalysis and materials science.
Used in Organic and Metallic Nanoparticle Synthesis:
Gold hydroxide is used as a reactant in the synthesis of a variety of perfluoroaryls, N-heterocyclic, and alkynyl compounds by reacting with C–H and N–H compounds and arylboronic acids. This application is particularly relevant in the field of organic chemistry and materials science.
Used in Preparing Potassium Aurate:
Gold hydroxide is used in the preparation of potassium aurate by heating auric hydroxide with concentrated KOH. Potassium aurate has potential applications in various chemical processes and reactions.
Production Methods
Gold(III) hydroxide is precipitated by mixing aqueous solutions of potassium auric chloride and sodium carbonate:2KAuCl4 + 3Na2CO3 + 3H2O → 2Au(OH)3 + 6NaCl + 2KCl + 3CO2 The product usually contains about three molecules of water of crystallization. It may alternatively be prepared by adding caustic soda solution to sodium auric cyanide: NaAu(CN)4 + 3NaOH → Au(OH)3 + 4NaCN.
Check Digit Verification of cas no
The CAS Registry Mumber 1303-52-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,0 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1303-52:
(6*1)+(5*3)+(4*0)+(3*3)+(2*5)+(1*2)=42
42 % 10 = 2
So 1303-52-2 is a valid CAS Registry Number.
