Sodium Nitrate FAQ
Q: What are the safety precautions for handling sodium nitrate?
A: Sodium nitrate should be stored in a cool, dry place away from combustible materials. Use protective gloves and goggles when handling, and avoid inhalation or ingestion. In case of contact with skin or eyes, rinse immediately with plenty of water.
Q: Is sodium nitrate the same as sodium nitrite?
A: No, sodium nitrate (NaNO3) and sodium nitrite (NaNO2) are different compounds. Sodium nitrate is used primarily as a fertilizer and food preservative, while sodium nitrite is commonly used in curing meats and has different chemical properties.
Q: How is sodium nitrate produced industrially?
A: Sodium nitrate is typically produced through the reaction of nitric acid with sodium carbonate or sodium hydroxide. It can also be mined as natural deposits, such as Chilean saltpeter, which is then purified for commercial use.
