Description
Magnesium hydroxide is an inorganic salt offered at a minimum assay of 95 % in Ph.Eur. quality for laboratory and pharmacopoeia-related work. It carries CAS number 1309-42-8 and EG nr. 215-170-3, with the empirical formula Mg(OH)₂, a molar mass of 58,32 g/mol, and a density of 2,41 g/cm³. The compound is As a sparingly soluble hydroxide, it is used where a defined magnesium base or buffer-related solid is required under pharmacopoeia-grade expectations. Clear specification of purity, identity, and physical data supports documentation in quality-controlled environments. This material is available from manufacturer Carl ROTH within the salts in pharmacopoeia quality range. The compact plastic unit suits bench-scale preparation, reference work, and general inorganic chemistry applications that call for magnesium hydroxide of at least 95 % purity conforming to Ph.Eur. requirements.
This article is part of Bases & alkalis, in Acids & bases.

Questions about Magnesium hydroxide, min. 95 %, Ph.Eur., 100 g, plastic
What is this article?
Magnesium hydroxide, min. 95 %, Ph.Eur., 100 g, 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.
Which category should I open next?
