Question

Which is the correct name for the compound (NH₄)2SO₄?

a. Nitrogen Hydrogen Sulfate
b. Nitrogen Hydrosulfate
c. Ammonium (II) Sulfate
d. Ammonium Sulfate

Answer 1

The compound (NH4)2SO4 is correctly named Ammonium Sulfate, resulting from two ammonium ions balancing one sulfate ion's charge.

Step-by-step explanation:

The correct name for the compound (NH4)2SO4 is Ammonium Sulfate. In this compound, the ammonium ion (NH4+) has a positive charge, and because sulfate (SO42-) has a double negative charge, two ammonium ions are required to balance one sulfate ion. Therefore, we conclude that the formula (NH4)2SO4 represents ammonium sulfate. This is an ionic compound composed of positively charged ammonium cations and negatively charged sulfate anions.
