MCQ
When acidified K2Cr2O7 solution is added to Sn2+ salts then Sn2+ changes to
- ASn
- BSn3+
- CSn4+
- DSn+
✓
Answer
- Sn4+
Explanation:
Thus, Acidified potassium dichromate will oxidize tin(II) to tin(IV)
$\text{Cr}_2\text{O}_7^{2-}+14\text{H}^++3\text{Sn}^{2+}\rightarrow2\text{Cr}^{3+}+3\text{Sn}^{4+}+7\text{H}_2\text{O}$
