Product Overview

Sulphuric Acid 95-97% AR (CAS No. 7664-93-9) is a concentrated analytical sulphuric acid reagent supplied within the stated concentration range. Its strong diprotic acidity supports digestion, acidification and conventional analytical reaction media, while its sulphate content can participate in precipitation or ionic matrix chemistry.

The AR grade is intended for conventional analytical digestion, reagent formulation, acid–base procedures and laboratory quality control. The 95-97% concentration range is appropriate for established wet-chemical methods requiring concentrated sulphuric acid.

Typical Applications

• Wet-chemical sample digestion.
• Preparation of acidic analytical reagent systems.
• Acidification in conventional laboratory analysis.
• Acid–base titration and neutralisation studies.
• Sulphate precipitation and solution-chemistry procedures.
• Laboratory QC and analytical method development.

Common Synonyms

• Sulfuric acid
• Oil of vitriol

Storage Conditions

Store tightly closed to minimise moisture exchange and preserve the specified concentration range. Use clean analytical handling to limit contamination that could affect reagent blanks or subsequent analyses.
