What is the reaction when gold and sulphuric acid are mixed?
Gold does not react with sulphuric acid under normal conditions. Gold is a noble metal and is resistant to corrosion by acids, including sulphuric acid.
How would you separate gold from a mixture of gold and copper filings?
One method to separate gold from a mixture of gold and copper filings is by using a process called gravity separation. This involves shaking the mixture in water to allow the gold, being denser, to settle to the bottom while the lighter copper filings float on top. The separated gold can then be carefully collected and dried.
What removes copper from gold?
One common method to remove copper from gold is through a process called cupellation, where the gold-copper alloy is heated in a furnace with lead, which combines with the copper to form a separate layer called "dore." Another method is through electrolysis, where an electric current is passed through the gold-copper alloy in a solution to separate the copper ions from the gold.
When nitric acid is added to detect the presence of copper present in ornamental gold. what is the compound of copper formed. why does not gold change?
when niric acid is added to copper the compound formed will be copper nitrite,gold does not change because nitric acid will not react with gold,but it react with any other materials.thish is the reason why gold does not change sathish s sathya
Can copper sulphate be prepared from copper metal and dilute sulphuric acid?
No, it cannot be prepared by this method under normal conditions. For preparing copper sulphate, copper should be added to the sulphate salt of a metal which is less reactive than copper like Mercury, silver and gold
What is the reaction when gold and sulphuric acid are mixed?
Gold does not react with sulphuric acid under normal conditions. Gold is a noble metal and is resistant to corrosion by acids, including sulphuric acid.
What acid will eat copper but not gold?
Nitric acid can dissolve copper but not gold. Gold is resistant to most acids, including nitric acid, which is commonly used to dissolve copper.
What is the acid used by goldsmiths for cleaning gold and silver ornaments?
its concentrated sulphuric acid
What salt will be made when gold metal is put into sulphuric acid?
nothing, gold does not react at all.

What is the word equation for gold reacts with water?
Gold can be dissolved only by a mixture of nitric and hydrochloric acids.
What salt will be made when gold metal put in sulfuric acid?
Nothing, gold doesn't react with sulphuric acid
Which metal will not react readily with hydrochloric acid?
Gold is a metal that will not react readily with hydrochloric acid. This is because gold is a noble metal, meaning it is resistant to corrosion and does not easily undergo chemical reactions with acids like hydrochloric acid.
Does Citric Acid react with gold If so what is the reaction between Citric Acid and copper Metal?
Citric acid does not react with gold. However, it can react with copper metal to form copper citrate, water, and carbon dioxide. The reaction involves the displacement of hydrogen from citric acid by copper to form copper citrate.
