Question

Match the elements in List I with appropriate element in List II.

Answer 1

A) $A{s}_2^{+3}{S}_3^{-2}+O_2^o⟶\stackrel{+5}{As}{O}_3^{-}+\stackrel{6}{S}\stackrel{-2}{O_4^{2-}}$

Net change of electrons in $As=+2$, $O=-2$, $S=+8⟶\left[1\right]$

B) $\stackrel{0}{I_2}⟶\stackrel{-1}{I^{-}}+\stackrel{+5}{{I{O}_3}^{-}}$

Net change of electrons in $I=+5,-1⟶\left[4\right]$

C) $\stackrel{+1}{H_{3}P{O}_2}⟶\stackrel{-3}{P{H}_3}+\stackrel{+3}{2H_{3}P{O}_3}$

Net change of electrons in $P=-4,+2⟶\left[2\right]$

D) $\stackrel{+1}{H_{3}P{O}_2}+NaOH⟶\stackrel{+1}{Na{H}_{2}P{O}_2}+4H_{2}O$

Net change of electrons in $P=0⟶\left[3\right]$
