Product Overview

Sodium Chloride 99.5% AR/ACS (CAS No. 7647-14-5) is a neutral inorganic chloride salt that provides a reproducible source of sodium and chloride ions for conventional analytical chemistry. Chloride undergoes well-established precipitation reactions with silver(I) and participates in ionic-strength, conductivity and solution-equilibrium systems. The chemically simple electrolyte is therefore useful both as a reagent component and as a model ionic species in wet-chemical procedures.

The AR/ACS grade is intended for analytical reagent preparation, precipitation chemistry, laboratory quality control and preparation of non-certified chloride working solutions. It may be used in argentometric method development or verification when sodium chloride is an appropriate chloride source.

Typical Applications

• Preparation of non-certified chloride stock and working solutions.
• Argentometric precipitation and titration method development.
• Silver chloride precipitation studies.
• Adjustment of ionic strength in conventional analytical systems.
• Conductivity and electrolyte-response investigations.
• Laboratory QC and analytical reagent preparation.

Common Synonyms

• Halite
• Common salt
• Table salt
• Rock salt
• Sea salt

Storage Conditions

Keep tightly closed and dry to maintain reproducibility of analytical weighing and solution preparation. Use clean dispensing equipment to prevent contamination by other halides or soluble ionic species.
