Vedclass · Answer

(D) The acidity of oxoacids is generally proportional to the oxidation state of the central atom. Calculating the oxidation states: For $H_2SO_3$: $2(+1) + x + 3(-2) = 0 \implies x = +4$. For $H_3PO_3$: $3(+1) + x + 3(-2) = 0 \implies x = +3$. For $HClO_3$: $1(+1) + x + 3(-2) = 0 \implies x = +5$. Comparing the oxidation states: $Cl (+5) > S (+4) > P (+3)$. Therefore,the decreasing order of acidity is $III > I > II$.

Arrange the acids $(I)$ $H_2SO_3$,$(II)$ $H_3PO_3$,and $(III)$ $HClO_3$ in the decreasing order of acidity.
