If you needed to make ultrapure silver from crude silver, where would you collect the pure silver metal in an electrolytic cell?
a. cathode
b. anode
c. connecting wires
d. power source

We will collect the pure silver metal at cathode.

Explanation:

In an electrolytic cell, we pass current due to which it electrolyze a given electrolyte. There are two reactions at two cathodes

a) at anode: oxidation

b) at cathode : reduction.

Now we can use electrolysis for refining of a crude metal. We make crude metal as anode (by connecting the negative terminal of battery). at this electrode the metal undergoes oxidation to produce metal ion.

Metal ion gets reduced at cathode, and gives solid metal from metal ion.

Thus we get pure metal at cathode.

distance, luminosity, brightness, radius, chemical composition, and temperature

ok whats the question if not i cannot you i need question and need a thing to answer
