Redox Reactions
When chlorine is passed through hot concentrated caustic soda solution, the oxidation number of chlorine in one of the products increases from:
Calculate the oxidation number of phosphorus in $$ P O_{4}^{3-} $$.
Let oxidation sate of phosphorus is $$x$$
$$ \stackrel{x}{P} O_{4}^{3-} $$
$$ x+(-2) \times 4=-3 $$
$$ x-8=-3 $$
$$ x=-3+8 $$
$$ x=+5 $$
Thus, O.S. of phosphorous in this ion is +5.
When chlorine is passed through hot concentrated caustic soda solution, the oxidation number of chlorine in one of the products increases from:
