Electrolytic Cell Basics

What is the name of the cell that converts electrical energy into chemical energy?

What is the name of the cell that converts chemical energy into electrical energy?

An electrolyte must contain mobile ions that act as mobile charge carriers to conduct electricity thus it is always in aqueous state.

• Gospel truth

• Fake news

• Hmmm...

• It is a philosophical question....

Answer explanation

An electrolyte is an ionic compound that is in molten or aqueous states.

This is because only in these two states, can the charge carriers in ionic compounds (i.e., the ions) move.

An electrode is solid and

is a metal (which could be inert like platinum or otherwise like any other metals) or

a non-metal which is an electrical conductor like graphite

A concentrated solution always contains H⁺ and OH^- ions.

• For sure, yes!

• For sure, no!

• I am having an existential crisis.

An electrolytic cell contains these parts:

a power supply,

an electrolyte,

connecting wires, and

two what?

In an electrolytic cell, a cathode attracts what ions?

• cations
• anions

• me!

• cathode is anti-social and rejects all toxic ions

Thus, a cathode is a negative electrode and connected to the _______ terminal of the power source.

Which process takes place at the cathode?

• Oxidation of anions which will produce hydrogen as or a metal deposit.

• Oxidation of cations which will produce either hydrogen gas or a metal deposit.

• Reduction of anions which will produce hydrogen as or a metal deposit.

• Reduction of cations which will produce either hydrogen gas or a metal deposit.
