EDTA (ethylenediaminetetraacetic acid) is not a secondary standard. It is a chelating agent commonly used as a titrant in complexometric titrations to determine metal ions in solution. The stability and selectivity of EDTA complexes make it a primary standard for this purpose.
The reaction equation between Zn^2+ and EDTA is: Zn^2+ + EDTA → Zn(EDTA)^2-
Tertrasodium EDTA is a chelating and preservative agent.
To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.
what is colour of Mg2plus- EDTA complex?
use heat to heat the solution and add EDTA slowly to dissolve it.
EDTA is considered a secondary standard because its purity needs to be verified by titration with a primary standard solution to determine its exact concentration. This is due to the fact that EDTA is hygroscopic and its concentration can vary due to absorption of moisture from the atmosphere.
