Concentration / Chemical Properties

• Normality: 10.00 N

• Molarity: 10.00 M (HCl is monoprotic → N = M)

• Approx. % w/w HCl: ≈ 30–32%

• Approx. density: 1.15–1.18 g/mL (varies by manufacturer)

Note: Solutions above ~10 M approach the upper limit of stable aqueous HCl concentration; fumes are intense.

Applications

• Strong acid digestion of metals and minerals

• Acidification in analytical workflows

• Harsh cleaning / descaling procedures

• Preparation of chloride-containing reagents

• High-normality titration standards

Storage Requirements

• Store tightly sealed in corrosion-resistant containers

• Keep in a cool, well-ventilated area

• Protect from heat, direct sunlight, and incompatible materials (bases, oxidizers, metals)

• Use secondary containment for added safety

Safety & Handling

• Highly corrosive to skin, eyes, respiratory system

• Emits strong acidic fumes—use only in a fume hood

• Wear chemical-resistant gloves, face shield, goggles, and lab coat

• In case of contact: rinse with plenty of water for ≥15 minutes

• Neutralize spills with sodium bicarbonate or similar mild alkaline material
