Mohr's salt has the formula
- A \(\mathrm{FeSO}_4 \cdot 7 \mathrm{H}_2 \mathrm{O}\)
- B \(\mathrm{FeSO}_4\left(\mathrm{NH}_4\right)_2 \mathrm{SO}_4 \cdot 6 \mathrm{H}_2 \mathrm{O}\)
- C \(\mathrm{Fe}\left(\mathrm{SO}_4\right)_3\left(\mathrm{NH}_4\right)_2 \mathrm{SO}_4 \cdot 6 \mathrm{H}_2 \mathrm{O}\)
- D \(\mathrm{MgSO}_4 \cdot 7 \mathrm{H}_2 \mathrm{O}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{FeSO}_4\left(\mathrm{NH}_4\right)_2 \mathrm{SO}_4 \cdot 6 \mathrm{H}_2 \mathrm{O}\)
Step-by-step Solution
Detailed explanation
When \(\mathrm{FeSO}_4 \cdot 7 \mathrm{H}_2 \mathrm{O}\) reacts with \(\left(\mathrm{NH}_4\right)_2 \mathrm{SO}_4\), it forms a double salt known as ferrous ammonium sulphate…
