Solutions in beakers

Postby Mary Becerra 2D » Tue Feb 06, 2018 8:34 pm

During the lecture on Monday, there was a graphic of two beakers with an electron flow filled with similar solution. What is this solution? I was assuming it is water but can it be any liquid?

Each beaker has a solution of respective ions for each electrode metal. So in a beaker with a zinc electrode, the solution it is in will contain Zn2+ ions. If it is a copper electrode, the solution contains copper ions. Of course you can't usually get pure metal ions on their own; they had to have come from some original compound. Because of this, there will be some anions in each solution, but they aren't really important and don't have a significant impact on the reaction.

Yes, the solvent of these solutions is typically water while the solute is the metal ions being transferred back and forth via the discharge of the battery.
