Is EDTA considered as a primary standard?
No. Chemical compounds have to fulfill a number of requirements before they can be classified and used as a primary standard: A primary standard in chemistry is a reliable, readily quantified substance. Features of a primary standard include: 1. High purity 2. Stability (low reactivity) 3. Low hygroscopicity and efflorescence 4. High solubility (if used in titration) 5. High equivalent weight 6. Non-toxicity 7. Ready and cheap availability Edta and particularly the sodium salts of EDTA which are frequently used do not fulfill the first requirement. Therefore the solution of EDTA has to be standardised against a known and accepted primary standard.

Why is iodine considered a trace element in seawater?
A trace element is considered is a specific element that contains less than 100 parts per million in a sample. In this case, the sample is seawater. According to my understanding, the presence of iodine is very limited in seawater. There is only 0.05 parts per million of iodine in seawater. As such, iodine is considered a trace element in seawater.
