Determine the oxidation states of the elements in the compounds listed. none of the oxygen-containing compounds are peroxides or superoxides. (a) h2so4 (b) ca(oh)2 (c) broh (d) clno2 (e) ticl4 (f) nah'

Answer :

Oxidation number or oxidation state : It represent the number of electrons lost or gained by the atoms of an element in a compound.

Oxidation numbers are generally written with the sign (+) and (-) first and then the magnitude.

Rules for Oxidation Numbers are :

Now we have to determine the oxidation state of the elements in the compound.

(a)

Let the oxidation state of 'S' be, 'x'

Hence, the oxidation state of 'S' is, (+6)

(b)

Let the oxidation state of 'Ca' be, 'x'

Hence, the oxidation state of 'Ca' is, (+2)

(c)

Let the oxidation state of 'Br' be, 'x'

Hence, the oxidation state of 'Br' is, (+1)

(d)

Let the oxidation state of 'N' be, 'x'

Hence, the oxidation state of 'N' is, (+5)

(e)

Let the oxidation state of 'Ti' be, 'x'

Hence, the oxidation state of 'Ti' is, (+4)

(f)

Let the oxidation state of 'Na' be, 'x'

Hence, the oxidation state of 'Na' is, (+1)
