Sodium Nitrate (NaNO₃) is a naturally occurring mineral used in fertilizers and food preservation, while Sodium Nitrite (NaNO₂) is mainly used for curing meats and preventing bacterial growth.
Sodium Nitrate vs. Sodium Nitrite

Key Differences

Sodium Nitrate (NaNO₃) is a salt composed of sodium ions and nitrate ions. It's known for its role in agriculture as a fertilizer. Sodium Nitrite (NaNO₂), on the other hand, consists of sodium ions and nitrite ions. It's crucial in the food industry for preserving and flavoring meats.

Sodium Nitrate is often used in the preservation of foods, especially in products like jerky and canned meats. Its ability to maintain color and prevent spoilage is notable. Sodium Nitrite is also a preservative but is more specifically used in curing meats like bacon and hot dogs, where it helps maintain a pink color and prevents the growth of harmful bacteria.
