QUESTION 13 We make a 1.0 M solution of an unknown acid, HX. With a pH meter, we determine that the pH of the solution is 5.00. Which of the following statements about the HX is true? HX is a weak acid with a Ka value of about 10–10. HX is a strong acid. O HX is a weak acid with a Ka value of about 10-5. HX would probably be a good acid-base indicator. HX is a weak acid with a Ka value of about 10-8.
