Question

What is the formula for ammonium sulfate?

Answer 1

The formula or chemical formula of a compound is going to represent the chemical elements which are present in the given chemical. Formula also represents how many numbers of the same types of elements are present in the chemical.

Complete answer:
- In the question it is asked to write the formula for ammonium sulfate.
- We are supposed to write the formula to represent the chemical symbols for ammonium sulfate.
- In the given chemical ammonium sulfate there are two parts, one part is cationic part and another part is anionic part.
- The cationic part is ammonium and the anionic part is sulfate.
- The chemical formula of ammonium is $NH_{4}^{+}$ and the chemical formula for sulfate anion is $SO_{4}^{2-}$ .
- The charge on the ammonium cation is ‘+1’ and the charge on the sulfate anion is ‘-2’.
- Now we have to write chemical formulas by combining the cation and anion.
- Means two moles of ammonium is going to combine with one mole of sulfate to balance the charges present on them.
- The chemical combination of two moles of ammonium and one mole of sulfate is as follows.
$2NH_{4}^{+}+SO_{4}^{2-}\to {{(N{{H}_{4}})}_{2}}S{{O}_{4}}$
- Therefore the chemical formula for ammonium sulfate is ${{(N{{H}_{4}})}_{2}}S{{O}_{4}}$ .

Note:
We can prepare the ammonium sulfate in the laboratory by treating two moles of ammonia gas with one moles of sulphuric acid. The chemical reaction which represents the preparation of ammonium sulfate is as follows.
$2N{{H}_{3}}+{{H}_{2}}S{{O}_{4}}\to {{(N{{H}_{4}})}_{2}}S{{O}_{4}}$
