Identify the type of reaction for the following: ${P_4} + NaOH + {H_2}O \to Na{H_2}P{O_2} + P{H_3}$

$Cl_2 + NaOH$ (dil. and cold) $\longrightarrow A + B + H_2O$. The anions of $A$ and $B$ are respectively . . . . . .

The reaction that takes place when $Cl_2$ gas is passed through concentrated $NaOH$ solution is:
