A reactivity series is a simple list, but in our plating tanks, nothing is so simple, a? The chart says zinc will displace copper, but with the impurities in our waste solutions, sometimes it is the copper that plates out first, no? I see it every day when the boss shouts about inconsistent coating. So trust the series for your school exam, but in my factory, the real answer is written by the dirty water.
