- A. \( P C l_{5}, P O C l_{3}, H_{3} P O_{3} \)
- B. \( P C l_{5}, P O C l_{3}, H_{3} P O_{4} \)
- C. \( \operatorname{sOCl}_{2}, \operatorname{POCl}_{3}, H_{3} P O_{3} \)
- D. \( P C l_{3}, P O C l_{3}, H_{3} P O_{4} \)
Step-by-step solution
The reactions describe the stepwise hydrolysis of phosphorus pentachloride. First, PCl5 reacts with water to form POCl3 and HCl. Then, POCl3 further hydrolyzes to H3PO4 and HCl. Thus, A = PCl5, B = POCl3, C = H3PO4.
