Question

Consider the following ions:
$S_2{O}_2^{2-},S_2{O}_3^{2-},S_2{O}_4^{2-},S_2{O}_5^{2-},S_2{O}_6^{2-},S_2{O}_7^{2-},S_2{O}_8^{2-}$

If the number of ions having $S–S$ or $S=S$ linkage be $‘x^{\prime }$ and the number of ions having $S–O–S$ linkage be $‘y^{\prime }$, the number of ions having peroxy-linkage be $‘z^{\prime }$.
Find the value of $\left(\frac{x}{y+z}\right)$.

Answer 1

The structures are given as:

So, $x=5$ and $y=1\left(S_2{O}_7^{2-}\right)$ and $z=1\left(S_2{O}_8^{2-}\right)$.
Therefore, $\frac{x}{z+y}=\frac{5}{2}=2.5$
