How will the pH of brine (aq. NaCl solution) be affected when it is electrolysed?

Options

  1. AThe pH of the solution will rise as NaOH is formed in the electrolytic cell.
  2. BThe pH will decrease (become more acidic).
  3. CThe pH will remain unchanged.
  4. DThe pH will fluctuate but eventually stabilize.

Correct answer

A. The pH of the solution will rise as NaOH is formed in the electrolytic cell.

Step-by-step solution

Correct Option is : (A) The pH of the solution will rise as NaOH is formed in the electrolytic cell.
