Question

Oxidation-number of sulphur in Caros acid is : (A) +6 (B) +4 (C) +8 (D) +7

Tardigrade Admin · Accepted Answer

Caros acid is H 2 SO 5 . It has a peroxide linkage, so, oxidation of S is <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/e899534de9b16356756c797651266a8e-.jpeg" /> Let the oxidation state of S is x H2 S O5 (one peroxide bond) +2+x+3(-2)+1(-2)=0 2+x-6-2=0 x-6=0 x=6

Q. Oxidation-number of sulphur in Caros acid is :

$+ 6$

$+ 4$

$+ 8$

$+ 7$

Caros acid is $H_{2} S O_{5} .$ It has a peroxide linkage, so, oxidation of $S$ is

Let the oxidation state of $S$ is $x$
$H_{2} S O_{5}$ (one peroxide bond)
$+ 2 + x + 3 (- 2) + 1 (- 2) = 0$
$2 + x - 6 - 2 = 0$
$x - 6 = 0$
$x = 6$
