me and my partner did an experiment of turning copper coins into 'silver' and 'gold'
we used this site or the info:
http://www.nuffieldfoundation.org/practical-chemistry/turning-copper-coins-silver-and-gold
But we're having trouble with knowing how to make the calculations of :
How much % brass, copper and steel is now in the coin after the experiment?
How much zinc dissolved and formed sodium zincate?
How much zinc was formed on the copper coin?
Can anyone please give us some suggestions on what we could do.
