Experiment overview in this experiment, you will conduct, observe, and measure the process of electroplating this process is used to deposit a layer of metal, such as chromium, copper, or gold, onto another metal. You should consider demonstrating burette technique, and give students the opportunity to practise this in this experiment a pipette is not necessary, as the aim is to neutralise whatever volume of alkali is used, and that can be measured roughly using a measuring cylinder.
