объяснение:
думаю так, но всё равно проверь
3 P (s) + 5 AuCl3 (aq) + 12 H2O (l) → 5 Au (s) + 3 H3PO4 (aq) + 15 HCl (aq)
Это окислительно-восстановительная (редокс) реакция:
3 P0 - 15 e- → 3 PV
(окисление)
5 AuIII + 15 e- → 5 Au0
(восстановле́ние)
P является восстановителем, AuCl3 является окислителем.
