from ethylenediamine (1,2-diaminoethane), formaldehyde, and sodium cyanide.[ This route yields the sodium salt, which can be converted in a subsequent step into the acid forms:H2NCH2CH2NH2 + 4 CH2O + 4 NaCN + 4 H2O → (NaO2CCH2)2NCH2CH2N(CH2CO2Na)2 + 4 NH3(NaO2CCH2)2NCH2CH2N(CH2CO2Na)2 + 4 HCl → (HO2CCH2)2NCH2CH2N(CH2CO2H)2 + 4 NaCl

How do you prepare 1mM EDTA from 0.1M EDTA?
0.1M is 1/10 molar whereas 1mM is 1 millimolar and thus 1/1000 molar. There is thus a 1:100 dilution. So 10:1000 would be the same. To a 1000ml volumetric flask, pipete 10mls of 0.1M EDTA solution. Make up to the mark with deionized water. Mix and shake and you will have 1000mls of 1mM EDTA solution.
How do you can prepare 0.5molar EDTA solution?
EDTA has a molecular weigh of 292.24g/mol. So if you want to make 1 litre for example of 0.5M EDTA, you'd weigh out 292.24*0.5 or 146.12g of EDTA and dissolve and fill to 1 litre with solvent
What is the final concentration of a edta solution if a 1l of 50x stock solution was made using 18.612g of edta mw 372.24?
the mass of the EDTA used to prepare 1L oi solution is 18.612g. The formula mass is 372.24 g/mol. Therefore concentration of the 50x solution is: 18.612 g 1 mol ----------- x --------- = 0.050000 mol/L = 50.000 mM 1L 372.24 g
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
How much quantity of EDTA dissolved in 1000ml to get 0.01 m solution of EDTA?
1 mole EDTA has 4 equivalents. 0.01 N EDTA = 0.01 equivalents/liter, so you need 0.01/4 = 0.0025 moles EDTA/liter.
How do you prepare EDTA N50 solution?
for 1 leter- dissolve 3.7225 gm EDTA in 1 leter boild out disttiled water
How do you prepare 1mM edta from 0.1M edta-Na2 solution?
You dilute it 1:10, then you take 1 part of that solution and mix it with 9 parts of the diluent. That will make the 1:100 dilution you need, incl. prevention of pipette inaccuracy.

How do you prepare one normal solution of potassium nitrate?
Dissolve 101.1 g of potassium nitrate in 1 litre of water
What is a normal solution?
A normal solution is a solution in which 1 gram of solute is dissolved in 1 liter of water
How can you standardise 0.01M edta?
EDTA can be standardized by using a number or reagents, although this is often unnecessary, as it can be purchased in pure form. Standardizing against magnesium is done by dissolving 0.24g magnesium in 25mL 1M Hydrochloric solution, diluting the mixture out to 1 liter, taking 25mL of that solution and adding 75mL of water, 2mL of pH 10 ammonia buffer and a pinch of indicator ground with salt. Then titrate the EDTA solution that is being standardized until the incicator solution turns blue. The purity of the EDTA solution will then be indicated by the amount of solution used, by using a table or calculation software.
How do you prepare 1 percent iodine solution?
hehehe
How do you calculate percentage of nickel which react with the EDTA?
