Q293

Which is not a chelating compound?

A.
EDTA
B.
CDMA
Answer
C.
EDDHA
D.
HEDTA

Answer: Option B

Solution

Answer: Option B
Solution:
A chelating agent is a chemical compound that reacts with metal ions to form stable, water soluble metal complexes.
EDTA – Ethylenediamine tetraacetic acid is a chelating agent.
EDDHA – Ethylenediamine-N, N'-bis (2-hydroxyphenyl acetic acid) is also a chelating agent.
HEDTA – Hydroxyethylenediaminetriacetic acid. It can also chelate to form salts.
Thus, CDMA is a nonchelating agent.
