Question

Determine the oxidation state of Cl in each species. Identify the oxidation state of Cl in C1,0,. Identify the oxidation state of Cl in AICI. Identify the oxidation state of Cl in Ba(C102), Identify the oxidation state of Cl in CIF..

Answer 1

In generally i) The sum of the oxidation states of all the atoms of ions in a neutral compound is equal to zero. The sum of the oxidation states of all the atoms in a charged compound is equal to charge on (") that compound- The oxidation state of an element, in an elementary state is equal to zero. Ex: S, Al, c is zero. In generally for I Group elements oxidation state te - +1. I Group elements oxidation state = +2. oxygen =-2, In peroxides al Halogens (C1, F, I, B8) = -1. use these sules to write oxidation numbers. For halogens exception: (CI, BY, I) halogen bonded with o (cl, B8, I) r E jie. If CI, BY, I bonded with 'o' or 'F' xidation number varies, *'F' is a 1' in any compound. Un

® clo In genexally 'o'oxidation number = -2 1:201 +7(-2) = 0 → acl = 14 - Cla Cl = +7 .cl oxidation number = 47 @ Ba (C102), Ba is and group element so`ta' .: +2+2 [c1+ 26-d)) = 0 2+2 (CI - 4) = 0. § 2 [C1 - 43 = -2 (C1 – 4) = - C1-4 = 44. Cl = 4-4 = +3 iCl oxidation number = +3 Scanned with el CamScanner

Alch In generall oy "Al=+" so (42) + 4 (CI) = -1 Bad HCl = -|-3 C -4 Cl = + 1" cl oridation number - 1 ® CIET ' ť onidation number in any compound = -1. :: Cl + 4 (-1) = +1 cl= 4+1 C1=45 i c oxidation number = +5
