EDTA used analytically is usually the disodium salt Na2H4Y 2H2O (372.24 g/mol), which is .... anyremaining EDTA titrant, Ca standard stock solution, and Zn unknown solution ...
EDTA is soluble in water.
B'coz all calculations done with CACO3 equivalents needs a standard factor to determine hardness.
Tertrasodium EDTA is a chelating and preservative agent.
No. Edta is Ethylenediaminetetraacetic acid
because EDTA is obey all conditions of primary standard except high purity
To determine concentration of EDTA.

Yes, these expressions are synonyms.
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.
Zinc oxide wil also do..
one is specific
I don't know the actual answer.But the below information will help you get a right answer.try to improve/correct the answer: HCl is a secondary standard solution.It is used in acid-base solution.On the other hand,EDTA is dissolved in pH 8.0.That's a perfect match for the HCl.EDTA chelates divalent cations and helps to inhibit DNAse.Thus,it is possible to get intake DNA. arif ashraf-biochem-DU-BD
HCl is not used as a primary standard
Iron (III) ions form a deep-coloured complex with a maximum absorption at about 525nm; this complex is used as the basis for the photometric titration of iron(III) ion with standard EDTA solution.
HSC is Higher Secondary Certificate which is 12th standard.....10th standard is called as SSC that is Senior Secondary Certificate.
