Calculate the oxidation number of sulfur in H_2SO_4 .

Calculate the oxidation number of sulfur in H2SO4\text{H}_2\text{SO}_4.

Options

  1. A+2+2
  2. B+6+6
  3. C+4+4
  4. D−2-2

Correct answer

B. +6+6

Step-by-step solution

Let the oxidation number of sulfur in H2SO4\text{H}_2\text{SO}_4 be xx.

The oxidation number of hydrogen is +1+1 and that of oxygen is −2-2.

The sum of oxidation numbers of all atoms in a neutral molecule is zero.

2(+1)+x+4(−2)=02(+1) + x + 4(-2) = 0

2+x−8=02 + x - 8 = 0

x=+6x = +6

Answer: +6+6
