Nitric Acid 70% (Electronic Grade)
1. Product Information
- Product Name: Nitric Acid HNO3 70%
- Chemical Formula: HNO3 70%
- Origin: China
- Packaging: 1400 KG/tank
- Appearance: Colorless liquid, with a distinctive pungent odor. In natural conditions, nitric acid appears light yellow due to nitrogen dioxide accumulation.
2. Properties:
- Nitric acid is a strong oxidizing agent. It reacts vigorously with cyanide, and powdered metals can explode and self-ignite when reacting with turpentine.
- At high concentrations, it causes skin burns by reacting with keratin proteins, turning the skin yellow. Neutralization turns it orange.
- It can react vigorously with metals to produce highly flammable hydrogen gas in air. When diluting, never add water to the acid instead, always add acid to water.
3. Applications:
- Commonly used in the electronics industry due to its higher purity compared to regular nitric acid.
- Used in the production of electronic components such as microchips and semiconductors.
- Also utilized in pesticide manufacturing, antibiotics, and disinfectants.
4. Safety Measures and Storage:
- Ensure full personal protective equipment (PPE) when handling nitric acid, including safety goggles, masks, hats, gloves, long-sleeved clothing, and shoes.
- Maintain a clean and ventilated workspace.
- Store away from flammable materials, organic compounds, and metals, in a dry, well-ventilated area away from direct sunlight.
- Ensure tightly sealed containers to prevent exposure to air.
