Question

When tin(IV) chloride is treated with excess of conc. hydrochloric acid, the complex ion$(SnC{l}_6{)}^{2-}$ is formed. The oxidation state of tin in this complex ion is?

• A. $+4$
• B. zero
• C. $-2$
• D. $-4$

Answer 1

The correct option is A $+4$

Let oxidation state of $Sn$ is $x$ and we know oxidation of $Cl$ is $-1$, so $x+6(-1)=-2,x=+4$.
