b. HPO42-(aq) + H2O (l) PO43-(aq) + H3O+(aq) = a. Between 0 and 1 B. The chemical formula of hydrobromic acis is HBr. What is the K a value for this acid? (The value of Ka for hypochlorous acid is 2.9 * 10-8. Nov 18 2022 08:12 AM 1 Approved Answer Mark B answered on November 20, 2022 4 Ratings ( 9 Votes) Get access to this video and our entire Q&A library, What is a Conjugate Acid? The pH of a 0.10 M solution of a monoprotic acid is 2.96. Calculate the Ka of the acid. BrO + HO HBrO + OH Kb = [HBrO] [OH]/ [BrO] = (x) (x)/ (0.800 -x) = 5.0 10 Since Kb is small compared to 0.800, we can neglect the x-term to simplify the calculation. What is Kb for the benzoate ion? Calculate the pH of a 0.410 M aqueous solution of hypochlorous acid. The ka of hypochlorous acid HClO is 3.5 \times 10^{-8}. General Chemistry - Standalone book (MindTap Cour Introduction to General, Organic and Biochemistry. Kb of (CH3)2NH = 5.4 104, What is the pH of a 0.200 M CH3NH3Br solution? The Ka for HC_2H_3O_2 is 1.8x10^-5, what is the value of Kb for HC_2H_3O^- ? What is the pH of an aqueous solution with H3O+ = 9.2 x 10-2 M? A 0.0115 M solution of a weak acid has a pH of 3.42. What is the pH of an aqueous solution with H+ = 7.8 x 10-9 M? Given that K_a for HBrO is 2.8 times 10^{-9} at 25 degrees C, what is the value of K_b for BrO^- at 25 degrees C? What is the pH of an aqueous solution with {H_3O^+} = 6 x 10^-12 M ? A)9.9 10-2 B)1.2 10-5 C)2.8 10-12 D)6.9 10-9 E)1.4 10-10 16) 17)The pH of a 0.55 M aqueous solution of hypobromous acid, HBrO, at 25.0 C is 4.48. (For hypobromous acid (HBrO) K_a = 2.00 times 10^{-9}). Get access to this video and our entire Q&A library, Acid-Base Equilibrium: Calculating the Ka or Kb of a Solution. Write the expression for each of the following in water: Round your answer to 1 decimal place.
