Question
When Cl2 gas reacts with hot and concentrated sodium hydroxide solution, the oxidation number ofchlorine changes from
Options
A.Zero to + 1 and zero to -3
B.Zero to +1 and zero to -5
C.Zero to -1 and zero to +5
D.Zero -1 and zero to +3
Solution
Cl2 + NaOH(hot conc.) → NaCl + NaClO3
In NaCl , oxidation no. of Cl is -1
and in ClO3- , oxidation no. of Cl is +5
In NaCl , oxidation no. of Cl is -1
and in ClO3- , oxidation no. of Cl is +5
