Question

Assign oxidation number to the underlined elements in the following species:

NaHSO₄

✓

Answer

$\begin{matrix}\ \ +1&+1&\text{x}&-2\\\Rightarrow\ \text{Na}& \ \ \text{ H} &\text{S}&\ \text{ O}_4\end{matrix}$

Then, we have

1(+1) + 1(+1) + 1(x) + 4(-2) = 0

⇒ 1 + 1 + x - 8 = 0

⇒ x = +6

Hence, the oxidation number of S is +6.
