For the electrochemical cell below, the half-cell on the left is the anode and the cell potential is 0.178 V at 25 .C.
What is the concentration of H*, x, in mol L-1? Note: The symbol M is an abbreviation for mol L-1.
Pt(s) | V2+(aq, 0.720 M) , V3+(aq, 0.650 M) | | H*(aq, XM ) | H2(g, 1.10 bar) | Pt(s)
Half reaction
E /V
2 H+(aq) + 2 e- - H2(8)
0.000
V3+(aq) + e- - V2+(aq)
-0.255
Enter a value accurate to 3 significant figures.
X = [H*] = Number
mol L-1

The identification of the anode is conditioned by the
question where it say that " the half-cell on the left
is the anode".
The lef / cell is the hydrogen cell . (anode )
