Problem: Assign an oxidation state to each atom in each species.(a) Cr(b) Cr3+(c) CCl4(d) SrBr2(e) SO3(f) NO3–

FREE Expert Solution

elemental form  O.S. = 0

ion  O.S. = charge

a) Cr

elemental form  O.S. = 0

b) Cr3+

O.S. = charge

O.S. = +3

c) CCl4

O.S. Cl = -1

O.S. C + 4(O.S. Cl) = 0

O.S. C + (-4) = 0

O.S. C = +4
