Answer 2

EDTA stands for ethylene diamine tetracetic acid. So, the structure would be R2NCH2CH2NR2 where the R groups are acetic acid moieties and there are 2 of the attached to each of the nitrogens. It is too difficult to actually draw it here. Google EDTA so you can see it.

Answer 3

Formula: C6H12N2(COOH)4
