Question

an arrhenius acid is best defined WHich is a net ionic equation for the neutralization of a week acid with a strong base? 19) What is the approximate value of the equilbrium constant, K_n for the neutralixation of pyride with hydrochloric acid, shown in the equation below? The K_b for pyridline is 1.8 times 10^-9. 20) Which of these neutralization reaction has a pH 7 when equal moles of acid and base are mixed. 21) When 50 mL of 0.10 M NH_4CI is added to 50 mL of 0.10 M NH_4CI is added to 50 mL of 0.10 M NH_3 relative to the PH of the 0.10 m NH3 solution the pH of the resulting solution

Explanation / Answer

18. D (HF weak acid and NaOH strong base)

19. (A)

20. (A) strong base is neutralized with weak acid using equal moles

21. remain the same because it forms a buffer system

22. (B)

23. (A) since strong acid and salt of a strong acid and strong base do not form a buffer solution.

24. (B) buffers can resist only a slight change in ph because of the presence of a weak acid or weak base in its constituents.

25. (B)

26. (D)
