How do you can prepare 0.5molar EDTA solution?
To prepare a 0.5 M EDTA solution, dissolve the appropriate amount of EDTA disodium salt dihydrate (molecular weight 372.24 g/mol) in water to achieve a final volume desired. For example, to make 100 mL of 0.5 M EDTA solution, you would dissolve 18.61 g of EDTA disodium salt dihydrate in water and adjust the volume to 100 mL.
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 disodium salt of EDTA preferred to EDTA?
The disodium salt of EDTA is preferred over EDTA because it is more soluble in water, which makes it easier to handle and use in aqueous solutions. Additionally, the disodium salt has a higher stability in a wider range of pH levels compared to EDTA alone, making it more versatile for various applications.
How much quantity of EDTA dissolved in 1000ml to get 0.01 m solution of EDTA?
To prepare a 0.01 M solution of EDTA in 1000 ml, you would need 37.22 grams of EDTA disodium salt dihydrate (C10H14N2Na2O8·2H2O) or approximately 0.1 moles. Dissolve the EDTA in water and make up the volume to 1000 ml to get a 0.01 M solution.
What is the equivalent weight of hydrogen per oxide?
The equivalent weight of hydrogen peroxide is 17 g/mol.
Gram equivalent weight of EDTA?
The gram equivalent weight of EDTA (Ethylenediaminetetraacetic acid) is calculated by dividing its molar mass by the number of acidic hydrogen ions it can donate. Since EDTA can donate 4 acidic hydrogen ions, its gram equivalent weight is typically 372 g/mol divided by 4, which equals 93 g/equivalent.
What is equivalent weight of disodium EDTA?
Well, honey, the equivalent weight of disodium EDTA is approximately 292 grams per mole. It's just a fancy way of saying how much of the compound is needed to react with one equivalent of a given reactant. So, if you're looking to do some chemistry magic, there's your answer.
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.

Write down the reaction equation of Zn2 plus and EDTA?
The reaction equation between Zn^2+ and EDTA is: Zn^2+ + EDTA → Zn(EDTA)^2-
What is tertrasodium edta?
Tertrasodium EDTA is a chelating and preservative agent.
How many grams of EDTA do you add to make a 3.7 percent EDTA solution?
To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.
What is colour of EDTA metal complex?
what is colour of Mg2plus- EDTA complex?
When edta is insoluble in distilled water then how to make 0.01N edta solution?
use heat to heat the solution and add EDTA slowly to dissolve it.
Why EDTA is not dissolved in water?
EDTA is sparingly soluble in water because it forms complexes with metal ions, reducing its solubility. The formation of strong metal-EDTA complexes makes it challenging for EDTA to dissolve in water because it ties up with metal ions in solution.
What is Equivalent weight of chlorine?
the equivalent weight of chlorine is 35.453, which is also it's atomic weight.
