Does gold dissolves in acid other than aqua regia?
Gold is generally resistant to most acids due to its low reactivity. However, it can dissolve in a few specific acids, such as a mixture of hydrochloric acid and nitric acid (aqua regia), which is the most well-known solvent for gold. Other than aqua regia, gold can also dissolve in certain complexing agents like cyanide, but this is not typical of traditional acids. In general, gold does not dissolve in simple acids like hydrochloric or sulfuric acid.
Which acid platinum dissolve?
Platinum is resistant to most acids, but it can dissolve in a mixture of hydrochloric acid (HCl) and nitric acid (HNO3), known as aqua regia. Aqua regia can effectively dissolve platinum by forming soluble platinum complexes. Additionally, platinum can be attacked by certain halogen acids, such as chlorine and bromine, under specific conditions.
Is indium highly radioactive?
Iridium is the least reactive material and also has a very high melting point. It can however react with Aqua Regia sometimes and at very high temperatures it reacts with Oxygen to form Iridium Dioxide. It is the most resistant metal to corrosion, acids and other harmful substances.
Why is sulphuric acid called king of chemicals?
Sulphuric acid is known as the "King of Chemicals" because it is the most reactive of the acids and bases.
What do acid do to topaz?
Most substances will react with some acid or another. Even glass will be dissolved by hydroflouric acid and even gold will dissolve in aqua regia. As for regular acids, I have put a sample of topaz in a hydrochloric acid solution and after three weeks, it was unchanged.
Is the element gold reactive or nonreactive?
It is reactive, but does not react to most chemicals.It does react to chlorine and aqua regia.
Will mylar dissolve in aqua regia acid solution?
No, mylar is a type of polyester film that is resistant to most chemicals, including aqua regia. Aqua regia is a highly corrosive mixture of nitric acid and hydrochloric acid commonly used to dissolve noble metals like gold and platinum, but it will not dissolve mylar.
Does aqua-regia etch silicon nitride?
No, aqua regia does not etch silicon nitride. Silicon nitride is chemically inert to most acids, including aqua regia, due to its strong covalent bonds. An alternative method, such as reactive ion etching, is typically used to etch silicon nitride.
Latin name for a mixture of 3 parts hydrochloric acid and one part nitric acid?
The mixture of HNO3 and HCl in a 1:3 ratio respectively is known as "aqua regia". Although both component acids are clear, they form an orange solution when mixed. Aqua regia is highly corrosive and is most often used to dissolve gold...it's about the only thing that will.

Is gold soluble?
The gold is only soluble in Aqua regia which is a mixture of one part Nitric acid and three parts Hydrochloric acid you lose the gamwe you do know anyone can put these answers
Does gold reacts with acids?
Gold does not react with most acids, including hydrochloric acid and sulfuric acid. However, aqua regia, a mixture of nitric acid and hydrochloric acid, can dissolve gold to form gold chloride. This property is often used in gold recovery and refining processes.
How do you prepare aqua regia?
1. Pour 150ml concentrated HCl (hydrochloric acid) in a polypropylene container. 2. Carefully and slowly add 50ml of concentrated HNO3 (nitric acid) to the HCl. 3. Aqua regia is prepared. To dilute it, you can add few milliliters of it to water. 4. This soultion can be used to dissolve most metals or to clean glass.
What happens when gold reacts with acid?
Gold does not react with most acids, including hydrochloric acid and sulfuric acid. However, it can be dissolved by a mixture of nitric acid and hydrochloric acid, a process known as aqua regia. This allows gold to be extracted and purified in certain chemical processes.
An acid used by the goldsmith for cleaning gold and silver ornamentals?
mixture of sulphuric acid and hydrochloric acid . this mixture is known as king of acids or tejab(hindi) . everything dissolves in it except gold and silver and glass .
What is the best acid to test for gold?
Nitric acid is commonly used to test for the presence of gold. Gold does not react with nitric acid, distinguishing it from other metals that may be present in a sample. However, please note that handling acids requires proper safety precautions, and it's essential to conduct such tests in a controlled environment.
Can you use sulfuric acid on gold?
Sulfuric acid can dissolve gold, but it is not the most efficient or common method for extracting gold from ore. Other chemicals like cyanide or aqua regia are often used for gold extraction due to their higher effectiveness and selectivity. Additionally, the use of sulfuric acid on gold can be hazardous and should only be done by knowledgeable professionals with proper safety measures in place.
