Question
Write a balanced equation for the hydrolytic reactions PCl5 in heavy water.
Solution
PCL5 + D2O→ POCl3 + 2 DCl
POCl3 + 3 D2O → D3PO4 +3DCl
therefore the net reaction can be written as:
PCl5 +4D2O → D3PO4 +5DCl
POCl3 + 3 D2O → D3PO4 +3DCl
therefore the net reaction can be written as:
PCl5 +4D2O → D3PO4 +5DCl
