Which of the following ions have a high tendency to pitting corrosion?

Which of the following ions have a high tendency to pitting corrosion? Correct Answer Chlorides, bromides, and hypochlorites

In practical applications, most pitting failures are caused by chloride ions, hypochlorites, and bromide ions. Oxidizing metal ions with chlorides are aggressive pitters. Cupric, ferric, and mercuric halides are extremely aggressive.
