What is the oxidation number of underlined species in P F ₆⁻ and V ₂ O ₇⁻⁴ ions respectively?
Options
- A+5 and -5
- B+5 and +5
- C-5 and +5
- D+3 and +3
Correct answer
B. +5 and +5
Step-by-step solution
Let oxidation number of P _ in PF ₆⁻=x aligned x+(6 -1) & =-1 x & =+5 aligned Let oxidation number of V in V ₂ O ₇⁴⁻=y aligned 2 y+(-2 7) & =-4 y & =+5 aligned
