Final answer:
If titration shows the ammonium hydroxide has the specified 25% ammonia content, the chemist is satisfied; if it is lower, they will be concerned due to potential stoichiometric issues in reactions like the Haber process.
Step-by-step explanation:
The chemist will make a decision about the batch of ammonium hydroxide received based on the results of titration. Titration is a process where a solution of known concentration is used to determine the concentration of another solution. If the titration results show that the ammonia content is 25% as specified, the chemist will be satisfied because the ammonia content matches the invoice (Option A).
However, if the titration results indicate that the ammonia content is lower than specified, the chemist will be concerned (Option B) as this might affect the stoichiometric calculations and the efficiency of chemical reactions that require ammonia.
As an example of such calculations, using gas laws, we can determine the number of moles of ammonia present in a system if we know the volume, temperature, and pressure. This is critical for reactions like the Haber process, which produces ammonia industrially. The balanced chemical equation of this process, N₂ + 3H₂ → 2NH₃, helps in understanding the stoichiometry involved in producing ammonia from nitrogen and hydrogen gases.
