    Preferred Chelating Agents

    When it comes to using chelating agents, what are your preferences? I know some use EDTA others Sodium Citrate. Are there others you prefer to use? Also, why do you prefer one over the other? I have been using Citric Acid and Sodium Hydroxide to make my own Sodium Citrate.
