Textbook Excercise 6L.3 Part D

[HilaGelfer_2H]

Hi

I hope all is well.

When doing 6L.3 part d, I was confused on how to balance the equations since we are not given whether the reactions occur at basic/acidic conditions. Are we supposed to assume one condition over the other?

Thank you so much for all your help and good luck studying :)

Since they give us the cells, they essentially tell us whether/which ions will be involved in the final redox rxn. For part d, since they give us OH- as part of the cell, we know that it occurs in basic solution.

Additionally, in order to balance a redox reaction in a basic solution, you add H2O molecules to whatever side of the equation is lacking Oxygen molecules, and then add double that amount of H2Os to the opposite side of the reaction, and then finally, add that same doubled amount of OH- molecules to the first side of the equation (whatever side you put the inital H2Os on) to balance your Hs.
