Problem: Write a balanced chemical equation for the following and classify the reaction. Mixing ammonium nitrate and sodium hydroxide solutions gives aqueous sodium nitrate, ammonia gas, and water.

FREE Expert Solution

Before balancing the chemical reaction, let’s first write the chemical formula of each of the compounds involved in the reaction.


Reactants:

Ammonium Nitrate

• Ammonium is the cation NH4+

• Nitrate is the anion NO3-

When ions combine, their charges or oxidation numbers crisscross to become subscripts

          • NH4+ will have a subscript of 1 from NO3- → NH4

          • NO3 will have a subscript of 1 from NH4+ → NO3

          • Subscript 1 is no longer indicated → NH4NO3


Sodium Hydroxide

• Sodium is metal Na. It forms ionic bond as Na+

• Hydroxide contains H (‘hydro’) and O (‘oxide) → OH-

When ions combine, their charges or oxidation numbers crisscross to become subscripts

          • Na+ will have a subscript of 1 from OH- → Na

          • OH- will have a subscript of 1 from Na+ → OH

          • Subscript 1 is no longer indicated → NaOH
