Description
Potassium carbonate is a high-purity anhydrous inorganic salt offered at min. 99 %, p.a., ACS for analytical chemistry and general laboratory use. It is identified by CAS number 584-08-7 and the empirical formula K₂CO₃, with a molar mass of 138,21 g/mol and a density of 2,43 g/cm³. The combined p.a. and ACS grade designation supports consistent assay performance in research, teaching, and quality-control laboratories. This reagent from manufacturer Carl ROTH is a free-flowing solid that is straightforward to weigh and dissolve for aqueous work. Clear specification data aid method documentation and inter-laboratory comparability. The practical plastic packaging suits everyday bench use and organised storage among other salts for analysis, helping laboratories maintain a dependable supply of potassium carbonate for routine and specialised procedures.

Questions about Potassium carbonate, min. 99 %, p.a., ACS, 500 g, plastic
What is this article?
Potassium carbonate, min. 99 %, p.a., ACS, 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.
Shelves beside this one are Metals, elements & oxides and Nanomaterials & quantum dots.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
