Gold Copper
May 14th, 2010
Is it possible to extract copper from a copper -gold alloy by NaOH?
you have a melt of copper – gold alloy and you want reduce the amount of copper from the alloy
You need an ionic compound with a cation less reactive than Cu to get it out of an alloy. Sodium is very reactive, so it wants to bond to things. It wants to hold onto its octet.
