Assign $A, B, C, D$ from the given type of reaction.
$H_3PO_3 \xrightarrow{\Delta} H_3PO_4 + PH_3 \uparrow$

Which of the following acids exhibits oxidation,reduction,and complex formation properties?

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:

$P_4 + 3KOH + 3H_2O \to PH_3 + 3KH_2PO_2$; In this reaction,phosphorus undergoes:

Write the balanced chemical equation for the reaction of $Cl_{2}$ with hot and concentrated $NaOH$. Is this reaction a disproportionation reaction? Justify.

Assign $A$,$B$,$C$,$D$ from the given type of reaction.
