NITRIC OXIDE Chemical Properties

State and Color: A colorless gas under standard conditions.

Odor: Odorless in nature, but reacts readily with oxygen to form nitrogen dioxide (NO₂), which has a pungent odor.

Density: Slightly greater than air (molar mass 30 g/mol, compared to an average of approximately 29 g/mol for air).

Solubility: Sparingly soluble in water (unlike other nitrogen oxides, such as NO₂, which are readily soluble in water).

NITRIC OXIDE Use

1. Industrial Preparation of Nitric Acid:

As a key intermediate, nitric oxide is a core component of industrial nitric acid synthesis.

2. Biomedical Field:

As an important signaling molecule in the body, NO participates in physiological processes such as vasodilation, nerve conduction, and immune regulation. It also has potential value in research on inflammation and neurodegenerative diseases.

3. Chemical Synthesis and Analysis:

In organic synthesis, NO can act as an oxidant or ligand to prepare specific nitrogen-containing compounds. In analytical chemistry, its characteristic reactions with certain substances (such as luminescence with ozone) can be used to detect the concentration of related gases.

4. Environmental Remediation:

In industrial exhaust gas treatment, NO can be converted into harmless nitrogen gas through specific reactions (such as selective catalytic reduction), reducing atmospheric pollution caused by nitrogen oxides (e.g., to prevent acid rain and photochemical smog).

5. Food Industry (Limited Applications):

Very small amounts of NO can react with myoglobin in meat to maintain its vibrant color. It has been used as a food additive, but due to safety restrictions, its use must adhere to strict standards.
