Drawing Cell Diagram

Postby Andrew Liang 1I » Thu Feb 27, 2020 2:55 pm

When drawing cell diagram do we need to put the coefficient of the molecules? Do we put H2O?

No we do not need to put in coefficients in the cell diagram nor do we need to include H2O since it is the solvent and we only focus on the gas,solid, and aqueous substances.

make sure to write the state of the compound but you don't need to include the coefficient which means you don't need to find the balanced equation unless asked for separately

No, you just need to include the compound and its state

I didn't realize that the cell diagram does not represent the order of the molecules in the reaction.
But a rule I can follow is that the side being oxidized is the anode, and whatever solid that is on that side should be on the side of the anode, right? And that if there is no solid then the electrode on the side of the anode is Pt(s), right?
Thanks!

No, you do not need to include the coefficient of the molecules. You only include their states.

Yes, the anode is always the side being oxidized. My TA told us to write the cell diagram with aqueous molecules in the middle closest to the salt bridge, and keep the solids on the outside. If there is no metal solid in the solution on either side, then you would add Pt(s).
