Anode and cathode in cell diagram

Postby Lucia H 2L » Sat Mar 17, 2018 1:20 pm

The following items are obtained from the stockroom for the construction of a galvanic cell: two 250ml beakers and a salt bridge, a voltmeter with attached wires and clips, 200ml of 0.008M CrCl3 (aq), 200ml of 0.12M CuSO4(aq), a piece of copper wire, and a chrome-plated piece of metal.

How would you go about setting up the cell for this? How do you know which is the anode and which is the cathode?

the one with the highest molarity is always the cathode!
so from this figure out half rxns from the tables and fill it in from there!

With this question, since both beakers will have aqueous solutions, wouldn't the chrome conductor be required in both beakers? How would you construct the cell with just a single chrome piece?

The copper wire is the solid in the other one!
