Pure element has zero oxidation number. When forming ions it is equal the charge of ion.
Oxidation number of chlorine is +7. oxidation number of O is -2.
KCLO3 the oxidation number of potassuim is +1, oxidation number of chlorine is +5 the oxidation number of oxygen is -2 and there are 3 atoms of oxygen KClO3=1+5+(-2)3=0 therefore the oxidation number of KClO3 =0 or neutral
Oxidation number of N is +3. Oxidation number of Cl is -1.
S = +2 oxidation state cl = -1 oxidation state
The oxidation number of Na in NaCl is +1, while the oxidation number of Cl in NaCl is -1.
as oxidation number of K is 1 and the molecule is neutral 1+ Cl=0 Cl= -1 Therefore, the oxidation number of Cl is -1
the oxidation number of the molecule HCl is 0.because H has Oxidation no +1 and Cl has -1 oxidation no in the HCl.
Ag +1, Cl -7
-1 for each Cl, +2 for Pt
-1 for each Cl +3 for N
+1 for Li and -1 for Cl
H has Oxidation no +1 and Cl has -1
