EDTA Solution N/50 (0.02N)

EDTA Solution N/50 (0.02N) is a standardized aqueous solution of disodium ethylenediaminetetraacetate, primarily used as a titrant in complexometric analysis, especially for determining concentrations of metal ions like calcium and magnesium in water hardness titrations.​

Properties

Concentration: 0.02N (N/50), which equals approximately 0.005M.

Appearance: Clear, colorless, odorless liquid.​

Physical state: Liquid at room temperature.​

Laboratory Use

Used for volumetric (complexometric) analysis due to its ability to form stable chelates with metal ions.​

Commonly paired with indicators like Eriochrome Black T for EDTA titrations of water hardness.​

Analytical Grade preparation for accurate and reproducible results.​

Safety

Non-corrosive and generally safe for laboratory practices, but standard lab safety protocols should be observed.​

Store at room temperature in tightly sealed containers to maintain concentration and reactivity.​

EDTA N/50 (0.02N) is an essential reagent in analytical chemistry laboratories for reliable metal ion quantification by complexometric titration.
