EDTA is a chelating agent that can bind with divalent metals. Based on what you have learned in this lab, answer the following questions: One EDTA molecule can bind with two calcium ion. [ Select ] EDTA can also bind with magnesium ion. [ Select ] Before EDTA titration, with the presence of the indicator calmagite, calcium solution will show a blue color, and upon EDTA titration to the calcium solution, the color will turn red once reached endpoint. [ Select ] There is no need to standardize EDTA solution since the concentration of EDTA is always accurate based on mass measurement. [ Select ] [ Select ] True False
