Answer:
When the solution pressure (Ps) of metal ions becomes more than that of osmotic pressure(Po) then the cations enter into the solution more quickly and leave a negative charge on an electrode.
Explanation:
What is electrode potential?
Electrode potential is defined as the potential difference that occurs between the electrode and the electrolyte.
What exactly is standard electrode potential?
When the concentration of all species included in a half cell equals unity, then the electrode potential is termed standard electrode potential.
What do you mean by Ps?
Ps here designates solution pressure, When in an electrolyte a metal is partially submerged then there is the establishment of a potential that we called it an electrode/electrolyte interface. There exists a tendency for metal ions for forming positive ions in solution. By this, the electrons get deposited on an electrode making it negatively charged.
What do you mean by Po?
Po represents osmotic pressure, in this case, the metal ions from the solution have a tendency to get deposited on an electrode and make it a positively charged electrode.
What happens when Ps is greater than Po?
As we know now, Ps is responsible for making an electrode negatively charged whereas Po is responsible for making an electrode positively charged. So, we can clearly say that when the solution pressure or Ps will be greater than that of the Osmotic pressure or Po, then there will be a negative charge on an electrode.
Hope it helps!!!
