Cell Diagrams

Postby Alexa Tabakian 1A » Sat Feb 23, 2019 4:13 pm

On some of the homework solutions, they add a completely random element to the cell diagrams. For example, on 14.15, the cell diagram shows KOH, however there is no KOH in the solution. Can someone please explain?

Ions such as K+ in KOH are used to balance charges between the cathode and anode. Because anodes are losing electrons to the cathode, the anode becomes more positively charged; we need a way to make sure the charges are equal so the reaction will keep going. This is where salt bridges and ions come in. In this case, the K+ will flow through the salt bridge to the cathode to reduce the positive charge in the anode.
