Question

question 8 of 10
what is the oxidation state of cl in hclo₃?

a. -1

b. +5

c. +6

d. -6

Explanation:

Step1: Assign known oxidation states

H = +1, O = -2 (standard states)

Step2: Set up equation for neutral compound

Let Cl oxidation state = \( x \). Sum of states = 0:
\( (+1) + x + 3(-2) = 0 \)

Step3: Solve for \( x \)

\( 1 + x - 6 = 0 \) → \( x = 5 \)

Answer:

B. +5
