We’re being asked to label each component of the voltaic cell:
Recall that a voltaic or galvanic cell is an electrochemical cell that is spontaneous and produces electricity.
Let's recall some parts of the galvanic cell:
Anode is in the negative side (left side of the diagram)
▪ Anode → oxidation
▪ oxidation half-reaction happens in the anode solution
▪ losing electrons → becoming more positive → anode dissolves away
Cathode is in the positive side (right side of the diagram)
A 1M solution of Cu ( NO3 )2 is placed in a beaker with a strip of Cu metal. A 1 M solution of SnSO4 is placed in a second beaker with a strip of Sn metal. A salt bridge connects the two beakers, and wires to a voltmeter link the two metal electrodes.
Which electrode gains mass and which loses mass as the cell reaction proceeds?
