Concentration cell textbook question 6N. 3A self test [ENDORSED]

[Samantha Chung 4I]

For 6N. 3A self test 7th editon, how do we know what is the product/reactant in Q as the question does not specify if the 1.0M of solution is on the left or right? Im assuming the saturated solution is the product, but why exactly is that the case?

[Chem_Mod]

Remember in class I discussed:

R ---> P

[R] concentration is higher in a concentration cell
[P] concentration is lower in a concentration cell

Also,

The Ag⁺_(aq) is forming (increasing) on the left (in the cell diagram) and therefore the product.

The Ag⁺_(aq) is decreasing on the right (in the cell diagram) and therefore the reactant.

so its correct that the anode is always on the left of the concentration cell right?

Yes.

[Philip]

So in a concentration cell, is the anode always the one with the lower concentration?

Thank you so much for this post! Since I am a more visual learner, the addition of the model really helped to clear things up for me!

@ phillip

I am not sure if you can say that the anode will always have the lower concentration, however, it would make sense since the electrons transfer from anode to cathode. in the cathode solution, sometimes precipitate builds up on the cathode due to the electron transfer and the reaction carrying out

R concentration is larger in the cell, while the concentration of P is lower in the cell.
