Sodium Nitrate

Sodium nitrate is an inorganic compound with the chemical formula NaNO3, which is a hygroscopic colorless and transparent triangular crystal. It decomposes when heated to 380 ° C. Very soluble in water and liquid ammonia, soluble in methanol and ethanol, very slightly soluble in acetone, slightly soluble in glycerin.

Fast-acting fertilizer for acidic soils, especially for root crops such as beets and radishes. Ammonium nitrate is not suitable for base fertilizer and seed fertilizer, but it is suitable for topdressing in dry fields.

Sodium nitrate, commonly known as Chile saltpeter or soda niter, is a white, crystalline, and highly soluble inorganic compound. It is widely used in agriculture, food preservation, and industrial applications.
