NaNO3 + H2O >
No reaction although it dissolves.
The reaction between NaNO3 and H2O (water) can be explained as follows:
When NaNO3 (sodium nitrate) is dissolved in water (H2O), it dissociates into its ions, Na+ and NO3-. The sodium ion (Na+) and nitrate ion (NO3-) will be surrounded by the water molecules. This process is known as hydration or solvation.
The balanced chemical equation for the dissolution of NaNO3 in water is:
NaNO3 + H2O -> Na+ + NO3- + H2O
In this equation, the Na+ and NO3- ions are separated from each other and surrounded by water molecules. The water molecules provide a solvent environment for the ions to move freely.
It is important to note that, under normal conditions, dissolving NaNO3 in water is an exothermic process, meaning it releases heat. As a result, the temperature of the water may increase slightly when the salt is added.
Overall, the interaction between NaNO3 and H2O results in the formation of hydrated sodium ions (Na+) and nitrate ions (NO3-), which are dispersed uniformly in the water solution.
