Description
Ammonia solution 25 % is an extra pure aqueous ammonia reagent with a minimum content of 25 %, CAS number 1336-21-6 and empirical formula NH₃ + H₂O. It has a molar mass of 17,03 + aq g/mol, a density of 0,907 g/cm³ and a boiling point of 38 °C, giving a well-characterised alkaline medium for everyday laboratory work. The preparation is supplied in a practical that supports safe handling, storage and dispensing at the bench. Available from manufacturer Carl ROTH in extra pure quality, this solution is widely used for pH adjustment, precipitation and complexation steps, buffer and cleaning baths, and general inorganic or analytical procedures that require a defined ammonia concentration. Consistent assay and documented physical data help laboratories maintain reproducible conditions in research, teaching and quality-control environments. The compact litre pack suits both single-user stations and shared reagent stores where reliable aqueous ammonia is needed without unnecessary bulk.

Questions about Ammonia solution 25 %, min. 25 %, extra pure, 1 l, plastic
What is this article?
Ammonia solution 25 %, min. 25 %, extra pure, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Bases & alkalis, inside Acids & bases, in Lab chemicals.
A base or an alkali is sodium hydroxide, potassium hydroxide, ammonia and their relatives, as solid or as solution. The carbonate that a hydroxide picks up from the air changes a titre. Concentration and purity are the specification. Concentrated alkalis attack skin and aluminium.
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.
