49 views

The main difference between sodium nitrate and sodium nitrite lies in their chemical composition and their respective uses. Sodium nitrate (NaNO3) is primarily used as a food preservative and in the manufacture of fertilizers and explosives. On the other hand, sodium nitrite (NaNO2), with one less oxygen atom, is also used as a food preservative, especially in curing meats to prevent bacterial growth and to maintain the meat's pink color. Safety and dosage are important considerations, as both compounds can be toxic in high amounts.
