Hint:. EDTA (ethylenediaminetetraacetic acid) is a tetraprotic acid. As the name suggests, the structure will consist of ethane groups attached to the two amine groups which will result in the formation of ethylene diamine. Also, the four hydrogen atoms are replaced by the acetic acid groups resulting in complex structure.
- The molecular formula for EDTA is ${{C}_{10}}{{H}_{16}}{{N}_{2}}{{O}_{8}}$ .
