Calculate the O.N. ofthe star marked elements in the following species/molecules.
$N a_{2} * S 4 O_{6}, K * M n O_{4}, H_{2} * S O_{5}, * C H_{2} C l_{2}$

Open in App

Solution

$N a_{2} S O_{4}$ Refer to image 01
Average Oxidation State: $\frac{5 + 0 + 0 + 5}{4} = 2.5$
$K M n O_{4} \Rightarrow [K M n O_{4}]$
$= n + 1 - 8 = 0$
$n = 7$
Oxidation State: $7$
$H_{2} S O_{5}$ Refer to image 02
The oxidisation state $= 16$
$C H_{2} C l_{2} \Rightarrow [C H_{2} C l_{2}]$
$\Rightarrow n + 2 - 2 = 0$
$n = 0$
