You will be using the disodium salt of EDTA (M.W. = 372.24 g/mole). It has been dried for 1
day at 80°C to drive off any superficial moisture. Transfer it in desiccator for an hour.
Weigh carefully about 1.95 g of EDTA (record to
the nearest 0.1 mg). Quantitatively transfer this into a 500 mL volumetric flask then add 2-3 mL
of pH 10 ammonia buffer. Fill the flask about halfway to the mark with deionized water and
swirl to dissolve. This process can take up to 15 minutes. Once dissolved, dilute to the mark
and then cap and invert the flask at least 6 times to get a uniform solution. Keep the solution
capped.
This solution is about 0.01M but for an exact value you need Standardization of this solution with Calcium Carbonate standard solution.

How do you prepare 1 M solution from 6 M solution?
It's simple to dilute a solution, just add more water. If you have one liter of 6 molar solution, and add another 5 liters of water, it becomes a 1 molar solution. You can also use M1V1 = M2V2 formula for dilution. For example, if you want to prepare 1 M of solution in 1 litre of water, then how much volume you need from the initial 6 M solution? Simply use the equation, (6 M) x (V1) = (1 M) x (1 litre) ---> V1 = (1 M) x (1 litre)/(6 M) = 0.167 L or 167 ml
