A: "true gold is not afraid of fire" is gold is not afraid of oxidation.
But gold will oxidize, in the halogen ion.
The mixture solution formed by halogen is corrosive to gold.
Its corrosion reaction is as follows:
Au + 2 X2 - > 2 aux (X: C1, Br, I)
AuX + KX - > KAuX2
Gold is not afraid of oxidation, but is afraid of halogens, which is the salt mist test and sweat (artificial fluid).
Test, so the electroplating, including the chemical nickel gold, needs to be protected by gold.
