WebAug 19, 2024 · A buffered solution contains 0.25M NH3 (Kb = 1.8 x 10-5) and 0.40M NH4Cl. Calculate the pH of this solution. The major species in the given solution are: Ammonia (NH 3) Ammonium cation (NH 4+) Chloride ion (Cl –) Water (H 2 O) Here the Cl – ion is a weak base and water can behave as acid as well as base. The calculations are as follows: WebSince NaOH is a strong base, it will react with the weak acid in the buffer to form its conjugate base. Therefore, we need to calculate how much of the weak acid is present in the buffer solution: moles of C6H5NH2 = concentration × volume = 0.231 M × 1.00 L = 0.231 mol. A buffer solution contains 0.341MC6H5NH3Cl and 0.231MC6H5NH2 (aniline). WebPart 2: Buffered solution. 1. Place ~350 mL of DI water in the other clean beaker. 2. Add methyl orange and bromothymol blue solutions to the water – about the same amount as for the non-buffered solution. 3. Add 50 mL of 6.0 M acetic acid to the mixture and stir — should turn orange indicating the solution is acidic. military term pog
