Description
Potassium carbonate is an anhydrous inorganic carbonate supplied at a minimum purity of 99 % in Ph.Eur. quality. It is identified by CAS 584-08-7 and EG nr. 209-529-3, with the empirical formula K₂CO₃, a molar mass of 138,21 g/mol and a density of 2,43 g/cm³. Laboratories employ this salt as a mild base, buffering component, drying aid or potassium source in synthesis, sample preparation and pharmaceutical-related work that calls for pharmacopoeia-grade material. supports straightforward dispensing for routine and development-scale tasks. Clear molar-mass and density values assist stoichiometric calculations and formulation design. Sourced from manufacturer Carl ROTH, the product fits inorganic salt inventories where Ph.Eur. alignment and high assay are required. Typical application areas include pH adjustment, carbonate-mediated reactions, analytical reagent preparation and process chemistry that depends on consistent potassium carbonate quality without introducing unnecessary hydrate water into the system.

Questions about Potassium carbonate, min. 99 %, Ph. Eur., 500 g, plastic
What is this article?
Potassium carbonate, min. 99 %, Ph. Eur., 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
Which category should I open next?
The category is Inorganic chemicals. The sub-category is Inorganic salts. The catalogue is Lab chemicals.
