What does 'α' represent in the equation Ka = c²α² / c(1-α)?

Options

  1. AThe equilibrium constant.
  2. BThe concentration of X– ions.
  3. CThe extent up to which HX is ionized into ions.
  4. DThe initial concentration of H 3 O+ ions.

Correct answer

C. The extent up to which HX is ionized into ions.

Step-by-step solution

In the equation Ka = c²α² / c(1-α), 'α' represents the extent up to which HX is ionized into ions.
