Question

Is ethylenediaminetetraacetatic acid (EDTA) a diprotic complexing agent?

Answer 1

I'm doing a research on total hardness and I was wondering, what happens to th molarity of EDTA if I didn't add enough acid to the calcium carbonate slurry?

Answer 2

Since this is not my area of expertise, I searched Google under the key words "<I>EDTA</I>" to get these possible sources:

http://en.wikipedia.org/wiki/EDTA

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
