Cell Diagrams

Postby Lizette Noriega 1H » Fri Feb 28, 2020 11:06 pm

Does it matter which side you place the reduced reaction and the oxidized reaction? I've come across multiple sources that switch the orientation of the anode and cathodes so I could use some clarification on that. Thanks!

When drawing a cell diagram, the anode is placed on the left side while the cathode is placed on the right side.

For cell diagram, anode always on the left, then salt bridge (||) then cathode

In a cell diagram, the anode (oxidation reaction) is on the left and the cathode (reduction reaction) is on the right.

It does matter.
The anode is always on the left and the cathode is on the right with a salt bridge symbolized by "||" in the middle.

A general rule of thumb my TA said was that the anode is usually on the left and the cathode is on the right.

Yes, it's absolutely critical that the anodes are placed on the left side of the salt bridge and cathodes on the right side of the salt bridge.

The anode is on the left and the cathode is on the right. This is the correct way to do it. I don't think I've ever seen it the other way, but I'm not completely sure. It may be a different convention for different cells that we haven't learned.

The anode would be on the left and cathode would be on the right. This way makes more sense as the flow of electrons goes from left to right. The electrons come from the anode side that is oxidized, taking to the other side for reduction.

In a cell diagram, the anode would be on the left and the cathode would be on the right, separated by || (the salt bridge).

I'm not sure what sources switch it up, but I would say in the context of this class the anode will stay on the left and cathode on the right

The cell diagram is written as the anode (oxidation reaction) first on the left side followed by the cathode (reduction reaction) similar to how a cell would be drawn.

When working with a cell diagram, the left must have the anode (oxidation) and the right must have the cathode (reduction).

Typically when writing a cell diagram the cathode (reduction) goes on the right and the anode (oxidation) goes on the left. Metals are typically placed on the outskirts of the cell diagram as well.

I just wanted to add to this question, are they also separated when it's a different phase? Can someone explain that aspect to me? Thank you.
