$3 H_3PO_2 \xrightarrow{\Delta} (X) + PH_3;$ The reaction is:

Fluorine reacts with ice and results in the change: $H_2O_{(s)} + F_{2(g)} \to HF_{(g)} + HOF_{(g)}$. Justify that this reaction is a redox reaction.

Observe the following reaction:
$Cl_{2(g)} + 2OH^{-}_{(aq)} \rightarrow ClO^{-}_{(aq)} + Cl^{-}_{(aq)} + H_2O_{(l)}$
Identify the correct statements about this reaction:
$I$. $Cl_{2(g)}$ is oxidized to $ClO^{-}_{(aq)}$
$II$. $Cl_{2(g)}$ is oxidized to $Cl^{-}_{(aq)}$
$III$. $Cl_{2(g)}$ is reduced to $ClO^{-}_{(aq)}$
$IV$. $Cl_{2(g)}$ is reduced to $Cl^{-}_{(aq)}$
The correct answer is:
