The oxidation state of chlorine is 5.
+5
It has plus 7 oxidation state.It is in highest oxidation state.
Chlorine shows many numbers. It dhows +3 in here.
I really dont know that is a hard question ask a teacher. ;)
I didn't know there was an element called Ci?? I presume u meant Cl (CL) Chlorine It is 0 if it exist as a free element. (Which means that it is 0 if is not chemically combined to anything) But if it is in a compound, it is usually -1 (minus one) e.g HCl (The oxidation state of Cl in HCl is -1 (negative one) But in ZnCl2 (The oxidation state of Cl is still -1 BUT there is two chlorine atoms inside the compound, so it is -1 x(times/multiply) 2 = which is -2. The oxidation state in ZnCl2 is -2)
The oxidation number of Sodium in the Na + ion = 1
-2 oxidation state
K = +1 oxidation state Cl = +3 oxidation state O = -2 oxidation state
it is an acid
acid
Fe = +3 oxidation state Cl = -1 oxidation state
