Answer:
(NH₄)₂SO₃
Explanation:
Data Given:
formula for "ammonium sulfite”
Solution
Ammonium sulfite consist of following atoms
Nitrogen = N
Hydrogen = H
Sulfur = S
Oxygen = O
Now we will look for the symbols of ammonium and sulfite
Ammonium = NH₄⁺
ammonium consists one nitrogen and 4 hydrogen atoms. it have overall 1 positive charge.
Sulfite = SO₃²⁻
it have one sulfur and 2 oxygen atoms. the overall charge is 2-.
Now we will write Both ammonium and sulfite ions together. the charges will are the combining power and will be written at the base of the alternate position formula unit.
(NH₄)₂SO₃
So 2 ammonium ions combine with one sulfite ion.
So the formula for “ammonium sulfite” is (NH₄)₂SO₃
