In comparing the speed of movement of lead ions to iodide ions, we can conclude the following:
1. Lead ions move slower than iodide ions.
2. The reason for this difference lies in the charge-to-mass ratio of the ions. Lead ions have a higher mass compared to iodide ions, making them move at a slower pace when subjected to the same conditions, such as in a solution undergoing electrolysis.
3. Since the speed of ions in a solution is influenced by their charge and mass, lead ions, being heavier, exhibit a slower rate of movement than lighter iodide ions.
4. This difference in speed can be attributed to the principles of electrochemistry, where the mobility of ions is determined by factors like mass, charge, and the medium through which they are moving.
In summary, the slower speed of movement of lead ions compared to iodide ions is due to the higher mass of lead ions, affecting their mobility in a given solution.
