How do you prepare 0.02N solution?
3.8 grams of EDTA salt in 1 liter of DI water made up using a volumetric flask will give you 0.02n or 0.01m of EDTA solution. normality*eq.wt*volume rqrd weight= 1000 then will get weight of the compound required for that normality
What is the basicity of EDTA?
the basicity of EDTA is 4
What is EDTA whole blood?
EDTA whole blood is whole blood that has been drawn into a tube with EDTA in it. The EDTA is added to transport samples and prevents the blood from clotting.
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 EDTA tube prevents clotting?
EDTA functions as an anticoagulant.
Gram equivalent weight of EDTA?
2
What is equivalent weight of disodium EDTA?
EDTA (Na2H2EDTA.2H2O) is 374.24g/mol Be careful not to confuse pure EDTA with the required EDTA used in the lab. C10H12N2O8•4Na is the correct chemical formula for lab use and is the MW above.
What is molecular weight of edta?
To accurately calculate the molarity of an EDTA solution you need to determine the number of moles present and liters of solution. Take these two totals and divide them to determine molarity.

Why EDTA is not dissolved in water?
EDTA is soluble in water.

EDTA functions as an anticoagulant.
What is tertrasodium edta?
Tertrasodium EDTA is a chelating and preservative agent.
Is sodium chromate the same as edta?
No. Edta is Ethylenediaminetetraacetic acid
