Is there a way to "electroplate" wood with copper?

The most common way to apply metals by electrodeposition to nonconductive materials is to apply a "strike" of underlying metal, usually nickel or copper, via a method like electroless plating. In ...

Why is silver cyanide used for electroplating

Note the free cyanide is highly toxic. Cyanide bound to metal ions is less toxic, often much less or even less toxic than table salt. Potassium_ferrocyanide $\ce{K4[Fe(CN)6]}$ has LD50 $\pu{6400 mg/kg}...

Why is silver cyanide used for electroplating

Silver cyanide is used for silver electroplating because of the concentration of the free silver ions in solution which is so low that it is not far from zero. Due to the high values of its complex ...

Why do we do electrolysis and electroplating using warm electrolyte?

ringo makes good points in his answer. Additionally, though, the increased temperature enhances mass transfer of ions to/from the electrode surfaces by at least two mechanisms: Higher temperature ...

Copper layer doesn't stick after Copper electroplating

There are a couple factors here: What you are using for an anode is probably the most important. If you’re not using copper, you’re depleting your copper sulfate electrolyte of copper ions. Use a ...

Copper layer doesn't stick after Copper electroplating

Roughen the deposition surface, perhaps by buffing with very coarse sandpaper or an abrasive scrub pad or similar. If the surface isn't rough enough, the deposited coating has nothing to mechanically ...

Why do we do electrolysis and electroplating using warm electrolyte?

The reasoning here is two-fold. The solubility of most electrolytes increases with temperature, and water's ionization constant also increases with temperature. On the whole this means more ions, and ...

Why can higher voltages lead to less efficient electroplating?

When you apply the required voltage for the desired cell, then your desired product is being produced, but if you provide an overpotential then you forced the other reaction to also occur(the ...

Why can higher voltages lead to less efficient electroplating?

There are two types of control of what reaction may occur: thermodynamic control and kinetic control. Thermodynamic control dominates in near-equilibrium conditions, which in case of electroplating ...

Choose electrolyte for electroplating

There are two issues here: First, you will be oxidizing water. You would end up making oxygen in most of those cases, before oxidizing your metal and making the cation you need. Second, even in ...

Side products during the electrolysis of Copper Sulfate?

There are a few key factors that I expect are contributing here: $\ce{CuSO4}$ concentration – If your $\left[\ce{Cu^2+}\!\right]$ in solution is low, then that will disfavor deposition, as permeakra ...

How is it possible to electroplate using an Al3+ solution, when water is a stronger oxidant?

No ! It is not possible to deposit aluminum by electrolysis of a water solution. It may be done in a solution of $\ce{AlCl3}$ in an organic solvent like toluene, but not in water. And even in toluene, ...

Copper plating surface color shifts from light to dark orange to black in less than 12 hours

You are correct that the copper is oxidizing. Electrolyte left over on the surface would promote that reaction just as it is well known to do with iron rusting, so check your rinsing and drying.

What is the difference between copper sulfate and copper sulfate pentahydrate?

How does increasing the Hydrogen Concentration of CuSO4 (electrolyte) affect electroplating of copper

In electrolysis, $\ce{Cu^{2+}}$ is reduced in two steps, first to $\ce{Cu^+}$ and later on to $\ce{ Cu}$. Of course $\ce{Cu^+}$ is automatically disproportioned into $\ce{Cu}$ and $\ce{Cu^{2+}}$ in ...
