There are various chemicals starting with N, including nitric acid, which is used as an industrial solvent and in the production of fertilizers; sodium nitrate, a common fertilizer; and nitrogen, a colorless and odorless gas that makes up about 78% of Earth's atmosphere.

Chemicals starting with N have diverse applications. Nitric acid, for example, is used in etching metals, refining petroleum, and producing dyes; sodium nitrate is employed in food preservation and pyrotechnics; and nitrogen is vital for plant growth and is used in the production of fertilizers and explosives.

Chemicals starting with N should be stored in cool, dry, and well-ventilated areas, away from incompatible substances. Nitric acid, in particular, should be handled with caution as it is corrosive and can cause severe burns. Nitrogen gas, on the other hand, is relatively inert and can be stored in pressurized containers.

When working with chemicals starting with N, it's crucial to wear protective gear, including gloves, goggles, and a lab coat. Proper ventilation is essential, and potential hazards like flammability and toxicity should be taken into account. Nitric acid, for instance, requires specific measures due to its corrosive nature.
