What is the oxidation number of carbon in $K_{2} C_{2} O_{4}$ ?

Options:

Answer:

Solution:

Let the oxidation number of carbon in $K_{2} C_{2} O_{4}$ be $x$ .

The oxidation number of potassium ( $K$ ) is $+ 1$ and that of oxygen ( $O$ ) is $- 2$ .

Since the sum of oxidation numbers of all atoms in a neutral molecule is zero, we have:

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

$2 + 2 x - 8 = 0$

$2 x - 6 = 0$

$2 x = 6$

$x = + 3$

The oxidation number of carbon is $+ 3$ .

Answer: +3
