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.
Why you use pH 10 buffer in EDTA titration and the indicator paper not be put into the solution?
A pH 10 buffer is used in EDTA titrations to ensure that the reaction occurs at a consistent pH that is optimal for the formation of metal-EDTA complexes. The indicator paper is not added to the solution because the color change of the metal-EDTA complex is independent of pH and will occur naturally when all the metal ions are chelated by the EDTA.
Why do buffers added in EDTA titration?
Buffers are added in EDTA titrations to maintain a constant pH of the solution. This is important because the formation of metal-EDTA complexes, which is critical in EDTA titrations, often requires a specific pH range to ensure accurate and precise results. Buffers help prevent pH changes due to addition of EDTA or metal ions, ensuring the reaction occurs under stable conditions.
What is the molarity of a solution that is made by dissolving 75.0 grams of MgCl2 in 500.0 milliliters of solution?
Need moles MgCl2 75.0 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.7877 mole MgCl2 ================now, Molarity = moles of solute/Liters of solution ( 500.0 milliliters = 0.5 Liters ) Molarity = 0.7877 moles MgCl2/0.5 Liters = 1.58 M MgCl2 solution --------------------------------
What does standardise EDTA mean?
Standardizing EDTA refers to determining the exact concentration of the EDTA solution by titrating it against a known concentration of a metal ion solution. This process ensures that the EDTA solution is accurately diluted or concentrated to achieve consistent and reliable results in complexometric titrations.
Why is Ammonia solution added while preparing EDTA solution?
Ammonia solution is added to increase the pH of the solution to create a favorable environment for the formation of stable metal-EDTA complexes. This helps in improving the efficiency of complexation and enhances the chelating properties of EDTA.

Why ammonia is added in preparation of EDTA solution?
Ammonia is added in the preparation of EDTA solution to create a slightly basic pH environment, which helps to maximize the stability of EDTA and improve its chelating ability. The ammonia also helps to prevent the precipitation of certain metal hydroxides that may interfere with the chelation process.
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.
Does mgcl2 is an aqous solution?
Yes, MgCl2 can form an aqueous solution when it is dissolved in water. MgCl2 dissociates into magnesium (Mg2+) ions and chloride (Cl-) ions in water, forming an aqueous solution.
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.

How much gm of disodium edta require to prepare 0.05 m disodium edta solution?
To prepare a 0.05 M disodium EDTA solution, you would need to dissolve 3.72 grams of disodium EDTA dihydrate (Na2C10H14N2Na2·2H2O) in enough water to make 1 liter of solution.

This process ensures that the EDTA solution is accurately diluted or concentrated to achieve consistent and reliable results in complexometric titrations.
Why we add buffer to standardization of ED-TA solution?
Buffers are added to systems in order to resist any minor changes in pH. EDTA is an acid, (ethylene diamine tetracetic acid), and so a buffer is used in order to maintain a certain pH even after the EDTA is added.
