What is the oxidation state of Sin SO 3 ^ 2- ?

Oxidation state of S in SO3^2- is +4

Explanation:

S in SO3^2-=

S = ?

O = -2

S + 3 moles of O * -2 = -2

S + (-6) = -2( it has charge -2)

S - 6 = -2

S = -2 + 6

S = +4

Note, the sign is very important

Don't confuse SO3 together with SO3^2-, the oxidation state of S in SO3 is + 6, how?

S = ?

O = -2

S + 3 * -2 = 0 ( because it has no charge)

S - 6 = 0

S = +6

And in SO3^2-

S = +4

The difference is that one has charge SO3^2- and the other doesn't SO3.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
