Electrolysis Questions & Answers

What is the equation for the reaction at the cathode during the electrolysis of molten lead(II) iodide?
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 negativ
Which of the following equations is the correct equation for the cathode half-reaction in this electrolytic cell?
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 wh
What is the negative electrode called in an electrolytic cell?
A) anode, at which oxidation occursPositive electrode is called anode. Negative electrode is known as cathode.
Why should a DC current be used in electrolysis?
The charges of the electrodes will be constant, hence the components will stay at the respective electrode
