Which of the following ions, that can reduce pitting corrosion?

Which of the following ions, that can reduce pitting corrosion? Correct Answer Hydroxide, chromate and silicate salts

Pitting is one of the most destructive and insidious forms of corrosion. The tendency of pitting can be increased with the presence of chloride, bromide, and hypochlorites. But this tendency can be prevented or minimized with the presence of hydroxide, chromate, and silicate salts.
