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 strong acid. HX is a weak acid with a K_a value of about 10^-5 HX is a weak acid with a K_a value about 10^-8. HX is a weak acid with K_a value of about 10^-10. HX would probably be a good acid-base indicator.
