Description
Borax A.R. (analytical reagent), also known as sodium tetraborate decahydrate, is a high-purity grade of borax specifically prepared for use in analytical and laboratory applications. It shares the same chemical composition as regular borax, consisting of sodium ions (Na⁺), tetraborate ions (B4O7²⁻), and ten water molecules bound to it. Borax A.R. is typically free from impurities that could interfere with analytical measurements or reactions, making it suitable for precise and accurate laboratory work, such as titrations, spectrophotometry, and chemical analysis.
