A swimming-pool worker wants the pool's pH to be 7.2. She comes by to test the water and finds that the pH is 9.2. What should she do to correct this situation?

  • What she should do to correct this situation is to add acid.
    Bases have pH levels over 7, and acids have pH levels under 7. So if she wants to lower the level of pH in the pool, she should add acid in order to neutralize the pH levels so that people can swim in the pool without their skin getting irritated or something even more severe.
