Vedclass · Answer

(A) In photosynthesis $(I)$: $6CO_2 + 6H_2O \xrightarrow{h
u} C_6H_{12}O_6 + 6O_2$. Here,the oxidation state of oxygen changes from $-2$ in $H_2O$ to $0$ in $O_2$,so $H_2O$ is oxidised.In the reaction of $H_2O$ with fluorine $(II)$: $2H_2O + 2F_2 ightarrow 4HF + O_2$. Here,the oxidation state of oxygen changes from $-2$ in $H_2O$ to $0$ in $O_2$,so $H_2O$ is oxidised.In the reaction of $H_2O$ with hydrogen $(III)$: No reaction occurs.In the reaction of $H_2O$ with $P_4O_{10}$ $(IV)$: $P_4O_{10} + 6H_2O ightarrow 4H_3PO_4$. This is a hydrolysis reaction,not a redox reaction.Therefore,$H_2O$ is oxidised in reactions $I$ and $II$.

Identify the reactions in which $H_2O$ is oxidised:
$I$. Photosynthesis
$II$. Reaction of $H_2O$ with fluorine
$III$. Reaction of $H_2O$ with hydrogen
$IV$. Reaction of $H_2O$ with $P_4O_{10}$
The correct answer is
