In dilute solutions (< 0.01 M), what is the relationship between the activity of hydrogen ions (H+) and molarity ([H+])?

Options

  1. AActivity of hydrogen ion is always greater than molarity.
  2. BActivity of hydrogen ion is always less than molarity.
  3. CActivity of hydrogen ion is equal in magnitude to molarity.
  4. DActivity of hydrogen ion has no relationship with molarity.

Correct answer

C. Activity of hydrogen ion is equal in magnitude to molarity.

Step-by-step solution

In dilute solutions (< 0.01 M), the activity of hydrogen ions (H+) is equal in magnitude to the molarity ([H+]).
