Question

an electrolytic reaction occurs in which chromium is plated onto an object. what is the cathode for the reaction? the chromium strip the solution the spoon the beaker

Explanation:

In an electrolytic cell for plating (electroplating), the object to be plated (the spoon here) is the cathode. Reduction (gain of electrons) occurs at the cathode, and \( \text{Cr}^{3+} \) ions gain electrons to deposit as Cr on the cathode (spoon). The chromium strip is the anode (where oxidation occurs, supplying \( \text{Cr}^{3+} \) or losing electrons), the solution is the electrolyte, and the beaker is just the container, not an electrode.

Answer:

the spoon
