Question
9. Consider a 0.15 M solution of H2SO4. Which of the following statements is NOT true? A) This solution would turn litmus to red. B) This solution could neutralize a base. C) This solution has a pH of 11.20. D) This solution could dissolve metal. E) none of the above 10. What is the concentration of the hydronium [Halo ons in a neutral solution? 11. What is the concentration of hydronium ions in an acidic solution? A) 0.0 M B) 1.0x10 M C) 1.0x10 14 M D) 1.0x10 7 M E) 1.0 M 12. What is the value of the ion product constant for water (Kw)? 13. What is the concentration of hydronium ions in a solution if the concentration of hydroxide ions is 5 x 10 4? 14. Which solution below has the highest concentration of hydroxide ions? A) p 7.00 B) pH J 2.49 C) pH 35.50 D) pH 0.12 E) pH 7.93Explanation / Answer
9. Option e).
10. [H3O+] = 1x10-7 M
11. Option D.
12. Kw = 1x10-14
13. [OH] = 1x10-14 / 5x10-4 = 2x10-11 M.
14. Option b). (If you want explanation, put it on other question)
