Why Mohr's salt is considered a primary standard?
The Mohr salt is more stable to oxidation of Fe2+ to Fe3+.
What is the primary standard apparatus in chemistry?
we use primary standard apparatus in chemistry lab to find accurate resultthe examples of primary standard apparatus arepippetteburreteVolumetric Flask
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.
Is hcl praimary standard or secondary standard?

Why iodine is not directly employed as the primary standard?
In order for a substance to be a primary standard it must be able to dissolve in water. Since iodine is unable to do this it cannot be used as a primary standard
Is hcl a primary standard or a secoundary standard?
HCl is a gas which is dissolved in water to form the solution the concentration expressed is very approximate so its not a primary standard.
