getting little to no Oxygen and Hydrogen/negtive side generating lots of ooky goo
Copper at the cathode is oxidized. (I apologize for misspeaking in the video, the oxidation occurs at the cathode in an electrolytic cell)

The diagram should include the source of electric current (normally a battery or DC source) and conductors (wires — which are unchanged by the passage of electricity), positive and negative electrodes (made from graphite or platinum) , and the electrolyte (insulator as solid, conductor as a liquid/aqueous and decomposed by electricity).
Question by : Give the sign of the electrodoes and the reaction that occurs at each for both voltaic and electrolytic cells.?
Can you please help me!?!?! I really need your help. If you could answers this as soon as possible that would help!!!!

Remember this: “A red cat ate an ox” (A pisgahchemist original)
REDuction occurs at the CATthode, OXidation occurs at the ANode
This is true regardless of the direction of flow of electrons, in other words, whether it is electrolytic or voltaic (galvanic).
The word “anode” (from the Greek for “the way in”) was developed for Michael Faraday to describe the electrode where the conventional current came from as it entered the substance to be electrolyzed.
The word “cathode” was also developed for Faraday and means “the way out” and was used to describe the electrode where the conventional current left the substance being electrolyzed.
Conventional current is the hypothetical flow of positive charge and is the opposite of electron flow.
Anions were defined as the ions that were attracted to the anode in an electrolytic cell. Cations were defined as the ions attracted to the cathode in an electrolytic cell.
The signs of the anode and cathode can be tricky. In an electrolytic cell a voltage is applied to the electrodes. The positive side of the power supply is attached to the anode, and the negative side to the cathode. In a voltaic cell, a “battery”, the positive electrode is the cathode and the negative electrode is the anode.
The best way to think of anode and cathode is in terms of oxidation and reduction. That works regardless of the electron flow direction.

This was a project for Alternative Fuels class. It was an attempt to create a hydrogen generator, for the purpose of providing a spark-ignition engine with a partial mixture of hydrogen gas. The video shows partial completion of the cell, containing one electrode pair. The finished cell is planned to have 8 pairs in series. The electrolyte is tap water (treated lake source) and sodium hydroxide (lye).

Question by annie: Do cations move to the cathode and anions to the anode in all electrochemical cells or just electrolytic?
I know that oxidation occurs at the anode and reduction at the cathode for all types of electrochemical cells, but I’m not sure about the migration of cations and anions?

A widespread misconception is that anode polarity is always positive (+). This is often incorrectly inferred from the correct fact that in all electrochemical devices negatively charged anions move towards the anode (hence their name) and/or positively charged cations move away from it. In fact anode polarity depends on the device type, and sometimes even in which mode it operates, as per the above electric current direction-based universal definition. Consequently, as can be seen from the following examples, in a device which consumes power the anode is positive, and in a device which provides power the anode is negative

a battery.
a cell in which the cell reaction is spontaneous.
a cell in which an electric current drives a nonspontaneous reaction.
a cell in which reactants are continuously supplied to the cell.
explain in the most simple words plz
If 4.8 x 10 ^ 5 g of Cl2 are obtained, what is the current in amperes?
I am trying to study for my final, and there are review final questions with no answers. I try to do some , but am not sure if thats the way to do it or if it is the right answer.
Thank You , I really appreciate your time.

Electrolytic injection is a new and exciting term for HHO, Brown’s Gas, water for fuel, hydrogen injection, and oxyhydrogen fuel cells. Billy Newsom of www.hhokitstore.com promotes this new key term in order to develop a more friendly term to be used in marketing, press releases, and in general terminology. Just as all industries have their specialized jargon terms, we already see many ugly phrases used to describe the systems and the gasses which supplement engine fuels with a mixture of hydrogen and oxygen from the electrolysis of water. But of the many technical terms out there, none of them are suitable for the general public… until now. Electrolytic Injection and electrolytic generators are some of these new phrases. See www.hhokitstore.com Coining the term Electrolytic Injection by Billy Newsom.
