About Gold Chloride Solution

Chloride IonGold Chloride Solutions are moderate to highly concentrated liquid solutions of Gold Chloride. They are an excellent source of Gold Chloride for applications requiring solubilized Compound Solutions Packaging, Bulk Quantity materials. American Elements can prepare dissolved homogeneous solutions at customer specified concentrations or to the maximum stoichiometric concentration. Packaging is available in 55 gallon drums, smaller units and larger liquid totes. American Elements maintains solution production facilities in the United States, Northern Europe (Liverpool, UK), Southern Europe (Milan, Italy), Australia and China to allow for lower freight costs and quicker delivery to our customers. American Elements metal and rare earth compound solutions have numerous applications, but are commonly used in petrochemical cracking and automotive catalysts, water treatment, plating, textiles, research and in optic, laser, crystal and glass applications. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. We also produce Gold Chloride. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

The number of electrons in each of Gold's shells is 2, 8, 18, 32, 18, 1 and its electron configuration is [Xe]4f142 5d10 6s1. Gold Bohr ModelThe gold atom has a radius of 144 pm and a Van der Waals radius of 217 pm. Gold was first discovered by Early Man prior to 6000 B.C. In its elemental form, gold has a metallic yellow appearance. Gold is a soft metal and is usually alloyed to give it more strength.Elemental Gold It is a good conductor of heat and electricity, and is unaffected by air and most reagents. It is one of the least reactive chemical elements. Gold is often found as a free element and with silver as a gold-silver alloy. Less commonly, it is found in minerals as gold compounds, usually with tellurium.


Chlorine is a Block P, Group 17, Period 3 element. Its electron configuration is [Ne]3s23p5. The chlorine atom has a covalent radius of 102±4 pm and its Van der Waals radius is 175 pm. Chlorine ModelIn its elemental form, chlorine is a yellow-green gas. Chlorine is the second lightest halogen after fluorine. It has the third highest electronegativity and the highest electron affinity of all elements, making it a strong oxidizing agent. It is rarely found by itself in nature. Chlorine was discovered and first isolated by Carl Wilhelm Scheele in 1774. It was first recognized as an element by Humphry Davy in 1808.
