Description
EDTA tripotassium salt is supplied at min. 99 % purity with CAS number 65501-24-8 and empirical formula C₁₀H₁₃K₃N₂O₈ · 2 H₂O. The molar mass is 442,56 g/mol and the EG number is 241-543-5. This tripotassium ethylenediaminetetraacetate dihydrate acts as a highly soluble chelating salt for complexing metal ions in laboratory synthesis, analytical sample treatment and preparation of sequestering solutions. The article is Sourced from manufacturer Carl ROTH, it provides a clearly specified K₃-EDTA dihydrate grade with established purity and identity data for routine chemical work. Typical applications include metal ion control, complexometric support and formulation of alkaline-compatible chelating media where potassium salts are preferred over sodium analogues. Use this product when min. 99 % assay, defined hydrate composition and reliable CAS/EG documentation are required for reproducible laboratory procedures.
This article is part of Acids, in Acids & bases.

Questions about EDTA tripotassium salt, min. 99 %, 100 g, plastic
What is this article?
EDTA tripotassium salt, min. 99 %, 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
Which category should I open next?
