Effect of adding H2SO4 to the cathode compartment:
Adding H2SO4 to the cathode compartment will increase the concentration of H+ ions in the solution. This will have an effect on the equilibrium of the cell reaction.
Impact on cell potential (E):
- The increase in H+ ions will lead to a higher concentration of reactants on the cathode side.
- This will shift the equilibrium towards the right, favoring the formation of Zn2+ ions and H2 gas.
- The increase in the formation of products will result in an increase in cell potential (E).
Effect on equilibrium:
- The increase in H+ ions will cause the equilibrium to shift to the right.
- More Zn2+ ions and H2 gas will be produced as a result of this shift.
- The equilibrium will be pushed towards the side with higher product concentration.
Therefore, by adding H2SO4 to the cathode compartment, the cell potential (E) will increase and the equilibrium will shift to the right. This will result in more Zn2+ ions and H2 gas being produced in the cell reaction.
