What is the pH of a 0.25 M HBrO (aq) solution? (pKa = 8.69) a. 5.90 b (The value of Ka for hypochlorous acid is 2.9 * 10-8. What is the pH of a 0.1 M aqueous solution of NaF? Calculate the pH of a solution (to 2 decimal places) which is 0.106 M in phenol, Ka = 1.0 x 10-10. Calculate the pH of a 0.00323 M solution of NaF, give that the Ka of HF = 6.80 x 10-4 at 25 degrees C. Part A Given that at 25.0 C Ka for HCN is 4.9 10?10 and Kb for NH3 is 1.8 10-5, calculate Kb for CN- and Ka for NH4+. - What is the OH- in an aqueous solution with a pH of 12.18? Was the final answer of the question wrong? HCN -----> H+ + CN-, Q:A 0.785M solution of the weak acid, hypoiodous acid, HOI, has a Ka of 2.32x10-11. (K_b for C_2H_5NH_2 = 4.7 times 10^{-4} at 25 degree Celsius). It is mainly produced and handled in an aqueous solution. Kb BrO- = Kw / Ka HBrO = (1 x 10^-14) / (2.0 x 10^-9) = 5.0 x 10^-6 . What is the, Q:The value pKw is 11.05 at 78 C. A certain organic acid has a K_a of 5.81 times 10^{-5}. Determine the Ka for the acid. Find Ka for the acid. To find a concentration of H ions, you have to. If one of the resulting ions is appreciably basic then it will hydrolyze as well to produce a basic pH for the salt solution. The Ka for hypobromous acid, HBrO, is 2.0 x 10-9. Which is the stronger acid in each of the following pair HBrO_2 or HBrO
