This is a great school project or weekend fun. Grow some silver crystals that you can see under a microscope! Use the princples of electrochemistry to create crystals out of silver metal, and watch them grow right before your eyes.
You already know how to make sulfuric acid with the metabisulfite and oxidizer method and you saw how to make copper sulfate from copper and sulfuric acid, so now try making sulfuric acid with these two in mind… with sulfuric acid by electrolysis of copper using an inert anode.
Watch this science video tutorial from Nurd Rage on how to make copper sulfate from copper and sulfuric acid in three ways. They show you how to make copper sulfate from copper and sulfuric acid using two chemical methods and one electrochemical method.
Various electrochemical reactions requires that anodes do not degrade when used. Carbon is cheap, but degrades easily and platinum is extremely expensive. In a previous video, you learned "How to make cobalt and manganese nitrates", and you saw that titanium could be used as a cathode, but not as an anode due to an effect called passivation.
Watch this science video tutorial from Nurd Rage on how to restore silver with electrochemistry. You can restore old silver with aluminum foil or a battery by simple electrochemistry.
Watch this science video tutorial from Nurd Rage on how to make silver different colors by electrochemical anodizing. Without using paint, you can give a silver surface various colors by anodizing it.
Start with a regular plastic toy gun, like a squirt gun or NERF gun. Then, spray paint it a matte black. Once it dries, take several different colors of rub'n'buff and apply with your fingers. Now, you have your own steampunk style ray gun! Or, High Velocity Electrochemical Propellant Device!
In the perpetual search for a renewable and convenient energy source, our bacterial friends have once again stolen the limelight.
The lemon battery has a rich history in many elementary science classes as a great example of an electrochemical reaction.
