The correct answer to this question is Pb²⁺ (l) + 2e⁻ → Pb (l) . Electrolysis is a technique that uses a direct electric current (DC) to create a chemical reaction that would otherwise not occur spontaneously. The cathode is the negatively charged electrode (while the anode is the positive side) and is where the reduction reaction takes place.
Iodide is a type of salt with the formula Pbl2. The 2e- refers to the electricity that runs through the cathode from the energy source, and two electrons cause the two positive iodide molecules to separate.
The answer to this is letter B. Electrolysis is the process by which chemicals go through decomposition. You can use this formula for this purpose: 2H2O + 2e- → H2 + 2OH. Electrolysis is very important in the separation of elements especially when certain processes need to be done. There are some chemicals that may need to be separated from each other depending on their purpose.
The equation’s purpose is to show that the solution of the electrode will change and will produce different results. This is evident through the results that are achieved wherein one electrode has produced gaseous hydrogen while the other electrode shows a basic solution.
