D) 9.89 20) 21) A solution with hydronium ion concentration (H+) = 1.60 10-12 M has on concentration (H+1 = 1.60 x 10-12 M has a hydroxide ion concentration [OH-] = __ statement or answers the question. LTIPLE CHOICE. Choose the one alternative that best completes 21) e that best completes the statement or answers the question. 22) What is the pH of a solution prepared by mixing 25.00 mL of 0.010 M CH3CO2 Na? Assume that the volume of the solu 10-5 for CH3CO2H. by mixing 25.00 mL of 0.10 M CH3CO2H with 25.00 mL of me that the volume of the solutions are additive and that Ka = 1.8 x 22 A) 5.74 B) 3.74 C) 4.75 D) 2.87

Answer 1

kindly post different questions separately. please rate

hydronium on = H30+ [H3O+] = 3,50 X 10 -3 M At 25°C [H3O+] [OH-] = KW = 10-14 [OH-] = 10-14 - 10-14 [OH-] 3.50 x 10-3 = 2.86 x 10-12M in an aqueoca solution is 2186 *10-12 M Hence, hydroxide ion concentration So, option A) is conect
