Description
Ammonia solution 20 % is a pure aqueous ammonia reagent with the empirical formula NH₃ + H₂O and CAS number 1336-21-6. It is supplied at a stated concentration of 20 % for general laboratory use where a moderately strong alkaline ammonia source is required. The molar mass is given as 17,03 + aq g/mol, and the density ranges from 0,92 to 0,94 g/cm³, supporting straightforward mass-to-volume calculations in preparation and process work. This grade is Typical applications include pH adjustment, complexation chemistry, cleaning and etching baths, and as a base in analytical and synthetic workflows. The material is identified under EG nr. 215-647-6 and UN number 2672. Produced by manufacturer Carl ROTH, the solution provides a clearly specified pure ammonia concentrate suitable for day-to-day wet-chemistry tasks. Pack presentation in plastic helps reduce breakage risk during transport and bench use while maintaining a practical working volume for multi-step procedures.

Questions about Ammonia solution 20 %, 20 %, pure, 1 l, plastic
What is this article?
Ammonia solution 20 %, 20 %, 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.
