Current Question (ID: 10662)

Question:

$\text{The oxidation states of the S atom in } \text{S}_4\text{O}_6^{2-} \text{ from left to right, respectively, are:}$

Options:

1. $+6, 0, 0, \text{ and } +6$
2. $+5, +1, +1, \text{ and } +5$
3. $+5, 0, 0, \text{ and } +5$ (Correct)
4. $+3, +1, +1, \text{ and } +3$

Solution:

$\text{Hint: When two same elements form bond then the oxidation state of both elements are zero.}$ $\text{The structure of the given compound is as follows:}$ $\text{The oxidation state of the extreme left and extreme right sulphur atom is } +5 \text{ respectively. The oxidation of state of the second and third sulphur atom is } 0.$
