You tell tell if a solution is supersaturated if it cannot dissolve any more solute at any given temperature. You can not “mix” the solution anymore to dissolve the solute. If it is saturated, you would be able to dissolve the solute.
Answer:
The overall cell potential must be positive.
Explanation:
What must be true for a spontaneous reaction in an electrochemical cell?
- The overall cell potential must be positive. YES. This is by convention.
- The overall cell potential must be negative. NO. By convention, a negative cell potential means the cell is not spontaneous.
- The cathode’s standard reduction potential must be positive. NO. It only has to be higher than the anode's standard reduction potential.
- The cathode’s standard reduction potential must be negative. NO. It only has to be higher than the anode's standard reduction potential.
