What is a Magnesium nitrate (Mg(NO₃)₂)?

Magnesium nitrate (Mg(NO₃)₂) is an inorganic salt formed from the reaction of magnesium and nitric acid. It typically appears as a colorless crystalline substance or white powder, commonly sold in its hexahydrate form (Mg(NO₃)₂·6H₂O), and is highly soluble in water. It is widely used in agriculture as a fertilizer, providing both magnesium and nitrogen to support chlorophyll production and photosynthesis in plants. It also functions as a dehydrating agent, drying agent, and occasionally as an oxidizing agent in laboratory settings.

Magnesium nitrate is an oxidizer, which means it can intensify fires if mixed with flammable materials. It is hygroscopic and should be stored in sealed containers in dry environments. Although relatively low in toxicity, it may cause irritation upon prolonged exposure, so protective gloves and goggles are recommended during handling.
