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.
What else can I help you with?
Why EDTA is secondary standard?
EDTA (ethylenediaminetetraacetic acid) is considered a secondary standard because it is not typically used as a primary standard due to its complexation properties and the difficulty in accurately determining its purity. Instead, it is standardized against a primary standard, such as calcium carbonate or sodium carbonate, which can be measured with high accuracy. Once standardized, EDTA can then be used reliably in titrations to determine concentrations of metal ions in solution. Its ability to form stable complexes with various metal ions makes it particularly useful in analytical chemistry.

Why EDTA ia secondary standard?
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.
