Write an overall equation for the acid-base reaction that would be required to produce the following salt. (NH4 )2 SO4

2NH₃(g) + H₂SO₄(g) → (NH₄)₂SO₄(s)

Explanation:

(NH₄)₂SO₄ → Ammonium sulfate

This salt comes from a weak base and a strong acid

Base → Ammonia

Acid → Sulfuric acid

The reaction is:

2NH₃(aq) + H₂SO₄(aq) → (NH₄)₂SO₄(aq)

This is an acid salt; the protons from the acid are gained by the weak base.

As sulfuric is a strong acid, the sulfate is the conjugate weak base (it has no reaction)

As ammonia is a weak base, the ammonium is the conjugate strong acid so in water, it can react as this: NH₄⁺ + H₂O ⇄ NH₃ + H₃O⁺       Ka

Hydroniums are released, that's why it is an acid salt

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
