P3+ arrow P5+ + 2e- Cl2 + 2e- arrow 2Cl- So, P is being oxidised from P3+ to P5+. So, it is acting as reductant. Cl is being reduced from Cl2 (0) to Cl-(-1). So, it is acting as an oxidant.

Q. Select the species acting as reductant and oxidant in the following.
$PC l_{3} + C l_{2} \to PC l_{5}$

$C l_{2}$ is oxidant, $PC l_{3}$ is reductant.

$C l_{2}$ is reductant, $PC l_{3}$ is oxidant.

Both are reductants.

Both are oxidants.

$P^{3 +} \to P^{5 +} + 2 e^{-}$
$C l_{2} + 2 e^{-} \to 2 C l^{-}$
So, $P$ is being oxidised from $P^{3 +}$ to $P^{5 +}$ . So, it is acting as reductant.
$Cl$ is being reduced from $C l_{2} (0)$ to $C l^{-} (- 1)$ . So, it is acting as an oxidant.

Q. Select the species acting as reductant and oxidant in the following. PCl3​+Cl2​→PCl5​

Cl2​ is oxidant, PCl3​ is reductant.

Cl2​ is reductant, PCl3​ is oxidant.
