Which of the following is true regarding the dissociation constant (Ka) for H 2 SO 4 ?

Options

  1. Aa1 K >10, indicating weak ionization
  2. Ba1 K = 1.2 × 10–2, indicating strong ionization
  3. Ca2 K >10, indicating weak ionization
  4. Da2 K = 1.2 × 10–2, indicating strong ionization

Correct answer

B. a1 K = 1.2 × 10–2, indicating strong ionization

Step-by-step solution

The dissociation constant (Ka) for the first ionization step of H 2 SO 4 is 1.2 × 10–2, indicating strong ionization.
