Please provide detailed solution and give the explanation of the concept..... A 1.42 L buffer solution consists of 0.176 M butanoic acid and 0.280 M sodium butanoate. Calculate the pH of the solution following the addition of 0.077 moles of NaOH. Assume that any contribution of the NaOH to the volume of the solution is negligible. The Ka of butanoic acid is 1.52 × 10-5. Note: The buffer solution consists of the weak acid butanoic acid, C3H7COOH, and its conjugate base butanoate, C3H7COO–. The added NaOH, a strong base, will react with a stoichiometrically equivalent amount of butanoic acid to produce butanoate. Start by determining the initial amount, in moles, of butanoic acid and butanoate in the buffer solution before the addition of NaOH.arrow_forward

ASK AN EXPERTASKScienceChemistryTris(hydroxymethyl)aminomethane [(HOCH2)3CNH2, or "Tris" for short] acts as a Brønsted- Lowry base (pK, = 5.92 at 25°C). Tris and TrisHCI are often combined to make a buffer in biochemical laboratories. %3D (a) At what pH do Tris buffers behave optimally (i.e., have equal capacity to neutralize acid and base additions)? (b) Tris buffer is normally used between pH values of 7.0 and 9.0. Calculate the ratio [Tris]/[TrisH+] at the extremes of the range. (c) A buffer is prepared by diluting 50.0 g Tris base and 65.0 g TrisHCI to a total volume of 2.0 L. What is the pH of the buffer? (d) What is the pH after 0.50 mL of 12 M HCI is added to a 200.0-mL portion of the buffer in part (c)?Tris(hydroxymethyl)aminomethane [(HOCH2)3CNH2, or "Tris" for short] acts as a Brønsted- Lowry base (pK, = 5.92 at 25°C).
