The Potassium Sulfate ACS Reagent by Dinâmica, available at LojaLab, is a neutral inorganic salt used as a source of potassium and sulfate in analytical and preparative procedures. The colorless-to-white solid is water-soluble and has high thermal stability. In the laboratory, it may be used in controlled-ionic-strength solutions, Kjeldahl digestions and precipitation or equilibrium studies involving K+ and sulfate ions.
Characteristics
- Anhydrous inorganic salt formed by two potassium ions and one sulfate anion
- Colorless-to-white solid that is soluble in water
- High melting point as 1069 °C
- Source of K+ and sulfate for inorganic solutions and matrices
- Analytical/ACS grade for procedures requiring low impurity interference.
Applications
- Preparation of potassium- and sulfate-containing solutions for chemical and instrumental assays
- Component of Kjeldahl digestion mixtures, where it helps raise the boiling temperature of the acidic medium
- Ionic-strength adjustment and studies of salt solubility, crystallization or equilibria
- Preparation of matrices and reagents in methods specifying analytical-grade potassium sulfate.
