Questions (Answer on another sheet of paper): 1. What happens to the mass of the anode during the electroplating process? (Hint: Refer to the diagram on page 2. Te th Other than being an electrical conductor, what properties should it have, or not have? (Consider: Rock salt is a very good electrical conductor, so it is a candidate for the anode. What would happen, though, to a bar of rock salt if immersed in water?) e material of which the anode is madé of any importance? 3. What about the cathode? The copper atoms are attracted to, and stick to, the cathode. The cathode needs to be a material that copper atoms will readily stick to. Copper itself is the obvious choice. That's why the electrodes are strips of copper (see photo #1). If the electrolyte in this experiment were silver nitrate, then. .. 3a) What would you suggest for the material of the electrodes? 3b) What changes, if any, would this have on the steps used in the calculation of the charge e? (If you do not already know, look up the charge on the silver ion.) 4. Some sets of equipment for electrolysis use two anode plates (connected together at the top), with the cathode placed between them. Of what advantage is such an arrangement? 5. What is the purpose of rinsing the cathode in clear water before air-drying (above a flame) and then weighing (procedure step 4)2
Explanation / Answer
Answer.
1. During the electroplating, anode loses mass, and cathode gains equivalent mass.
2. The electrodes should be electron conductors. Rock salt does not conduct when it is in solid phase. Being immersed into a water it will dissolve, and will not serve as an electrode.
3. a) if the electrolyte is a silver nitrate, the anode should be silver and the cathode should be silver or copper.
b) The charge of the silver ion is (+1).
4. In a such arrangement the inequalities of deposited metal distribution are minimized.
