Nitric Acid (HNO₃) at a concentration of 68% is a common chemical reagent with various applications in industries such as manufacturing, agriculture, and laboratory research. Here are the general specifications for Nitric Acid 68%:

### Chemical Properties:

- **Concentration:** 68% ± 1%

- **Chemical Formula:** HNO₃

- **Molecular Weight:** 63.01 g/mol

- **Density:** 1.41 g/cm³ at 20°C

- **Boiling Point:** Approximately 121°C

- **Melting Point:** -42°C

- **Vapor Pressure:** 6.2 kPa at 20°C

- **pH:** < 1 (strongly acidic)

- **Appearance:** Clear, colorless to slightly yellow liquid

- **Odor:** Pungent, acrid

### Purity and Impurities:

- **Purity:** ≥ 99.0%

- **Chlorides (Cl):** ≤ 0.001%

- **Sulphates (SO₄):** ≤ 0.002%

- **Heavy Metals (as Pb):** ≤ 0.001%

- **Iron (Fe):** ≤ 0.0005%

### Physical Properties:

- **Solubility in Water:** Miscible in all proportions

- **Reactivity:** Highly reactive, especially with organic materials and metals

### Safety and Handling:

- **Hazard Classification:** Corrosive, oxidizing agent

- **Personal Protective Equipment (PPE):** Gloves, safety goggles, face shield, acid-resistant clothing

- **Storage Conditions:** Store in a cool, well-ventilated area, away from incompatible substances such as organic materials, reducing agents, and alkalis

- **First Aid Measures:** Immediate washing with plenty of water in case of skin or eye contact; seek medical attention if necessary

### Applications:

- **Industrial Use:** Production of fertilizers, explosives, and dyes

- **Laboratory Use:** Analytical chemistry, etching of metals

- **Cleaning Agent:** Removal of rust and scale from metals

Always refer to the Material Safety Data Sheet (MSDS) for detailed safety and handling information specific to the nitric acid you are using.
