Description
Magnesium sulphate heptahydrate is an extra pure laboratory chemical with CAS number 10034-99-8 and the empirical formula MgSO₄ · 7 H₂O. It has a molar mass of 246,48 g/mol and a density of 1,67 g/cm³, with a boiling point above 70 °C. This crystalline hydrate is used in analytical chemistry, buffer and stock-solution preparation, and as a defined source of magnesium and sulphate ions in aqueous systems. supports economical bulk handling for routine laboratory consumption. Available from manufacturer Carl ROTH and identified under EG number 231-298-2, the salt is offered in extra pure quality for general laboratory procedures. Its stated composition and physical data help maintain consistency when preparing standard solutions or performing precipitation and crystallisation work. The heptahydrate dissolves readily in water, making it practical for media components, reagent stocks, and teaching or research workflows that require controlled magnesium sulphate concentrations.

Questions about Magnesium sulphate heptahydrate, extra pure, 2.5 kg, plastic
What is this article?
Magnesium sulphate heptahydrate, extra pure, 2.5 kg, 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?
