What happens to gold when dipped into a solution of copper sulfate?
When gold is dipped into a solution of copper sulfate, a redox reaction occurs where copper ions in the solution gain electrons and are reduced to solid copper metal. The gold does not react and remains unchanged in the solution.
What is the reaction of Gold with copper sulfate?
At STP, there will be no reaction. Gold is much less active than copper so there will be negligible gold sulfate formed by substitution. Gold is the lowest metal in the electrochemical series, so it will not react chemically with salts of any other metal.
What happens if you add zinc to copper sulfate And what happens if you add gold to copper sulfate?
Adding zinc to copper sulfate will result in a displacement reaction that will create copper metal to precipitate as a solid. CuSO4(aq) + Zn(s) ---> ZnSO4 + Cu(s) This reaction is quite exothermic too, meaning it will give off alot of heat - enough to make it too hot to hold the reaction beaker in bare hands.
Which of these metals will replace the Iron in an Iron Solution a copper b gold c Lead d Zinc?
Zinc is the metal that will replace iron in an iron solution through a displacement reaction because it is more reactive. Copper, gold, and lead are less reactive than iron and would not displace it in a solution.
Will zinc precipitate copper from gold chloride?
Yes, zinc can displace copper from gold chloride solution through a redox reaction. The zinc will react with the copper ions in the gold chloride solution, leading to the formation of copper metal and zinc chloride.
A metal which cannot replace zinc from zinc sulfate solution?
Copper, silver, and gold are three safe examples.

What happens when gold is put in copper sulfate?
Any reaction occur when gold is put in copper sulfate.

What metals or metal compounds will not react with copper sulfate?
Metals like gold, platinum, and silver typically do not react with copper sulfate. Additionally, metal compounds that are less reactive than copper, such as zinc oxide or aluminum oxide, will not react with copper sulfate either.
Will zinc precipitate copper from gold chloride?
Yes, zinc can displace copper from gold chloride solution through a redox reaction. The zinc will react with the copper ions in the gold chloride solution, leading to the formation of copper metal and zinc chloride.
What would happen to a gold ring dropped into a solution of copper nitrate?
When a gold ring is dropped into a solution of copper nitrate, a redox reaction takes place where the gold would dissolve as gold ions, and copper from the copper nitrate would deposit onto the ring. This results in the gold ring becoming plated with a layer of copper.
What is an example of replacement?
to replace copper with gold
When zinc metal is placed into a solution of copper sulphate a pinky brown metal is formed but when a piece of silver metal is placed into another solution of copper sulphate no change is observed Why?
Silver is lower in the reactivity series than Zinc and therfore cannot displace the Sulphate from the Zinc. But on the other hand zinc is higher than copper, and when displacing the sulphate from the copper it changes colour due to the reaction. Reactivity series(metals): Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Silver Gold Platinum
Can anyone explain the science behind copper into gold or show a website that tells the explanation?
Copper into gold, means putting copper powder in gold salt solution. Because copper is closer to hydrogen then gold, in the electromotive scale, it will dissolve, freeing the gold
