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.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
