Nothing. Gold is a noble metal- it is not displaced by iron.
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.
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.
If there is one sulphate molcule, there will be 2 gold atoms.
Presumably you mean gold sulphate? Gold sulphate does not exist except as part of a complex salt.
gold sulphate
You don't.
24karot gold layered. Its fake. (dipped in gold)
it means that its not solid gold its plated or dipped in gold
gold + sulphuric acid = gold sulphate + hydrogen :)
usually means gold dipped
no gold is not a solution
A part of this light is absorbed.
