In the following reaction correct change in phosphorus is explained by, 4 P + 3 K O H + 3 H 2 O → 3 K H 2 P O 2 + P H 3

Options

  1. AP is oxidized as well as reduced
  2. BP is oxidised only
  3. CP is reduced only
  4. DNone of these

Correct answer

A. P is oxidized as well as reduced

Step-by-step solution

P is oxidized as well as reduced, its oxidation number changes from 0 ( P-atom ) to +1 ( K H 2 P O 2 ) and -3 ( P H 3 ) .
