Question

Calculate oxidation states of underlined species in folloiwng.
i) C,H,OH ii) 10 iii) PCI
5​

Answer 1

Explanation:

i) If you mean by C2H5OH

C = ?

H = +1

O = -2

Let c become x, since this is a neutral Compound so the overall charge is 0

2x + 5 -2 + 1 = 0

2x = 4

x= +2 , so C has a +2 charge

ii) If you mean by IO

Let I as x

O is usually -2

so x-2=0

so x= +2

iii) PCl5

Cl always have -1

so let P = x

x + 5(-1) = 0

x= 5
