EDTA, or ethylenediaminetetraacetic acid, captures or "chelates" metal ions out of solution, preventing them from participating in unwanted side reactions. In GTE buffer, EDTA is added at 10mM. Its primary purpose is in the buffer to round up free zinc, magnesium, and calcium, thereby preventing DNA degradation by certain pathways that require those metals.
To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.
use heat to heat the solution and add EDTA slowly to dissolve it.
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.
Tris, or tris(hydroxymethyl)aminomethane, is commonly used as a buffering agent in GTE (Green Tea Extract) solutions. It helps maintain a stable pH level, which is important for preserving the integrity of active compounds in the extract. Tris also aids in maintaining the desired solubility of components in the solution.

To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.
In this case sodium chloride does not have any buffering role.
use heat to heat the solution and add EDTA slowly to dissolve it.
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.
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.
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.
Tris, or tris(hydroxymethyl)aminomethane, is commonly used as a buffering agent in GTE (Green Tea Extract) solutions. It helps maintain a stable pH level, which is important for preserving the integrity of active compounds in the extract. Tris also aids in maintaining the desired solubility of components in the solution.
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.
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.
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.
MgCl2 is added to a solution of EDTA to prevent the formation of insoluble metal hydroxides when titrating with EDTA. This helps to ensure that the EDTA only chelates with the target metal ions in the solution without interference from other metal hydroxides. MgCl2 acts as a masking agent for other metal ions present in the solution.
