Select the p K_ a value of the strongest acid from the following.

Options

  1. A2.0
  2. B4.5
  3. C1.0
  4. D3.0

Correct answer

C. 1.0

Step-by-step solution

The acidic strength of an acid increase with ionisation. The value of p K_ a is inversely proportional to ionisation constant ( K _ a ) . The acid with p K_ a value 1.0 is strongest.
