Acid or base?

Will we always be given whether a solution is basic or acidic for balancing redox reactions? If we aren't, what are all the ways we'd be expected to know to determine if the solution is acidic or basic?

Yes, we will be given this information. If it is not explicitly stated acidic or basic, they may give the pH of the solution in which the reaction occurs.

I would expect that we would be given whether we are balancing the redox reactions in basic or acidic conditions. All of the textbook problems follow this format, so thus, Dr. Lavelle will probably follow a similar format on the final.

It will be given, but you might have to do some Ka pKa manipulation to find out, so make sure you remember how

Yes, we will be given that information as it is necessary to determine how to balance the redox rxns. In some cases, we might be given the pH or even pka or pkb to determine pH.

We should be given the information in the question whether it is basic or acidic, whether it is explicitly stated or they give us the pH.
