Okay, I'm gonna sound like a chemistry nerd for this it here it goes. I heard you can make copper II hydoxide by doing electrolysis on water with copper electrodes. I also heard that you can increase the conductivity by adding baking soda but not salt becuase this would introduce chlorine
Other websites tell me that if you do electrolysis on saltwater you get copper chloride becuase you introduced chlorine but, then woudn't you get the copper chloride AND copper II hydroxide? How do you only get one? I'm confused.

In the presence of chlorine you will get copper chlorine because chlorine is a stronger ligand than water. If you want to get copper hydroxide then you should do electrolysis in distilled water. If you want to get copper chloride then add NaCl to the water and do electrolysis.

You will get CuCl2 because Cl- has a higher affinity for Cu than OH-, in the competing reactions, CuCl2 dominates.
