How do you prepare 1 M EDTA solution?
You will be using the disodium salt of EDTA (M.W. = 372.24 g/mole). It has been dried for 1day 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 tothe nearest 0.1 mg). Quantitatively transfer this into a 500 mL volumetric flask then add 2-3 mLof pH 10 ammonia buffer. Fill the flask about halfway to the mark with deionized water andswirl to dissolve. This process can take up to 15 minutes. Once dissolved, dilute to the markand then cap and invert the flask at least 6 times to get a uniform solution. Keep the solutioncapped.This solution is about 0.01M but for an exact value you need Standardization of this solution with Calcium Carbonate standard solution.
Why you have to add buffer before titration with EDTA?
Adding a buffer solution before titration with EDTA helps to maintain a constant pH which is crucial for the formation of metal-EDTA complexes. The buffer solution prevents any fluctuations in pH that could affect the accuracy and precision of the titration results.

How do you measure permanent hardness by EDIT titration?
To measure permanent hardness by EDTA titration, first add a buffer solution to the water sample to maintain a stable pH. Then, titrate with standardized EDTA solution until the color changes indicating the endpoint. The volume of EDTA required to reach the endpoint can be used to calculate the concentration of the ions causing permanent hardness in the water.
How do you reduce the amount of acid in a solution?
Add a base or a buffer into the solution.
How you can do EDTA titration reaction?
To perform an EDTA titration, first prepare a solution containing the analyte (the substance being measured) and a suitable indicator, such as Eriochrome Black T. Add a standardized solution of EDTA to the analyte solution until the endpoint is reached, indicated by a color change in the indicator. The volume of EDTA solution added can be used to calculate the concentration of the analyte based on the stoichiometry of the reaction.
Is EDTA is water soluble if not than how will you prepare your solution?
Yes, EDTA is water-soluble. To prepare a solution, you can simply add the desired amount of EDTA powder to water and stir until it is completely dissolved. If you encounter issues with solubility, you can adjust the pH of the solution using sodium hydroxide or hydrochloric acid to help dissolve the EDTA.

How do you prepare 5mM EDTA of 100ml solution?
5mM = 0.005 moles 100 mL = 0.1 Liters Molarity = moles of solute/Liters of solution 0.005 M EDTA = X moles/0.1 Liters = 0.0005 moles EDTA =_____________ Now, look up the molecular formula for EDTA and find how many grams needed to add to your 100 mL.
What substance would you add to NaHCO3(aq) to form a buffer solution?
You would add a weak acid, like acetic acid (CH3COOH), to NaHCO3(aq) to form a buffer solution. The weak acid will react with the bicarbonate ion in NaHCO3 to maintain a stable pH.
