Product Name: Sodium hydroxide solution
Concentration: 0.1 N (0.1 mol/L)
Physical Properties: Clear, colorless, and odorless liquid.
Key Use: A secondary standard solution specifically prepared for precision titrations (Acidimetry) and fine pH adjustments in laboratory analysis.

Safety & Hazards

Classification: Classified as Corrosive and an irritant to skin and eyes.
Health Risks: Direct contact causes skin and eye irritation. Although less concentrated than 1.0N, it can still cause chemical burns upon prolonged exposure.
First Aid Measures: Immediately flush affected eyes or skin with plenty of water for at least 15 minutes. If swallowed, rinse mouth thoroughly and seek medical advice.

Handling & Storage

Storage: Store in tightly sealed plastic containers (HDPE) in a cool, dry place. Avoid prolonged storage in glass containers and do not use glass stoppers. Keep away from strong acids.
Precautions: Always wear standard PPE, including gloves and safety goggles. Seal the container immediately after use to prevent the absorption of atmospheric $CO_2$, which leads to a decrease in actual concentration.
