Calcium nitrate reacts with several substances, and its reactivity depends on the specific conditions. Here's a breakdown:
-
Water: Calcium nitrate is hygroscopic, meaning it readily absorbs moisture from the air. When it dissolves in water, it releases heat, making the process exothermic.
-
Incompatible Materials: Calcium nitrate is incompatible with the following:
- Strong Acids: Such as hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3). Reactions with these acids can release toxic fumes or generate hazardous byproducts.
- Metal Salts: Can potentially lead to precipitation reactions depending on the specific metal salt involved.
- Combustibles: Because calcium nitrate is an oxidizer, it can accelerate the burning of combustible materials, leading to fire hazards.
In summary, while calcium nitrate readily dissolves in water, it should be kept away from strong acids, metal salts, and combustible materials due to potentially hazardous reactions.
