Which of the following is the strongest acid?

Options

  1. ACIO 3 (OH)
  2. BCIO 2 (OH)
  3. CSO(OH) 2
  4. DSO 2 (OH) 2

Correct answer

A. CIO 3 (OH)

Step-by-step solution

As you go from left to right in the periodic table, the acidic strength goes on increasing. Also, as you increases the oxidation state of the central atom, the acidic strength increases. The more the electronegativity and oxidation number of the central atom (Cl), more is the acidic character.
