Auric acid is a chemical compound that is widely used in various industries. It has a unique structure and properties that make it useful in many different applications. In this article, we will explore the definition and meaning of auric acid, its origin, and its associations.
Definitions
Auric acid is a chemical compound with the formula HAuO4. It is an oxoacid of gold, which means it contains oxygen and hydrogen atoms bonded to a gold atom. Auric acid is a yellow, crystalline solid that is highly soluble in water and other polar solvents.
Auric acid is a strong oxidizing agent and can react with many different substances. It is used in the production of gold nanoparticles, as a catalyst in organic reactions, and in the electroplating of gold.
Origin
The name auric acid comes from the Latin word for gold, “aurum”. It was first synthesized in the early 1800s by the French chemist Louis Jacques Thénard. Thénard discovered that auric acid could be produced by treating gold metal with nitric acid.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, auric acid is “a yellow crystalline compound HAuO4 obtained by treating gold with nitric acid and used as a reagent and as a source of gold for electroplating.”
The Oxford English Dictionary defines auric acid as “a yellow crystalline compound of gold and oxygen, used in the production of gold nanoparticles and as a catalyst in organic reactions.”
Associations
Auric acid is commonly associated with the production of gold nanoparticles. These nanoparticles have unique optical and electronic properties that make them useful in many different applications, including biomedical imaging, drug delivery, and cancer therapy.
Auric acid is also used as a catalyst in organic reactions. It can help speed up chemical reactions and make them more efficient. This makes it a valuable tool in the production of many different chemicals and materials.
Synonyms
Some synonyms of auric acid include gold(III) oxide hydrate, hydrogen aurate, and auric hydroxide.
Antonyms
There are no direct antonyms of auric acid, but it can be contrasted with other oxoacids of gold, such as aurous acid (HAuO2) and gold peroxide (Au2O3).
The same root words
The word “auric” comes from the Latin word for gold, “aurum”. Other words with the same root include “auriferous” (containing gold) and “aurumvorax” (a mythical creature that devours gold).
