- B \(\mathrm{Fe}\left(\mathrm{SO}_4\right)_3\left(\mathrm{NH}_4\right)_2 \mathrm{SO}_4 \cdot 6 \mathrm{H}_2 \mathrm{O}\)
- C \(\mathrm{MgSO}_4 \cdot 7 \mathrm{H}_2 \mathrm{O}\)
- D \(\mathrm{FeSO}_4\left(\mathrm{NH}_4\right)_2 \mathrm{SO}_4 \cdot 6 \mathrm{H}_2 \mathrm{O}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{FeSO}_4\left(\mathrm{NH}_4\right)_2 \mathrm{SO}_4 \cdot 6 \mathrm{H}_2 \mathrm{O}\)
Step-by-step Solution
Detailed explanation
Mohr's salt is a double salt known as ferrous ammonium sulfate. Its chemical formula is \(\mathrm{FeSO}_4 \cdot (\mathrm{NH}_4)_2 \mathrm{SO}_4 \cdot 6 \mathrm{H}_2 \mathrm{O}\). Comparing this with the given options, the correct formula corresponds to…
