Sodium nitrate occurs naturally as saltpetre and is produced industrially by reacting nitric acid with sodium carbonate or sodium hydroxide.
It is a substance that is easily soluble in water and poorly soluble in ethanol, and is mainly used as a heat medium for heating and cooling systems, glass defoaming agents, raw materials for fertilizers, raw materials for dyes, and food additives.
Also, because it is a strong oxidizing agent, there is a risk of fire or explosion if it reacts with flammable or reducing substances.
NaNO3
