REPORT YOUR ANSWER TO 2 DECIMAL PLACES. DO NOT INCLUDE UNITS. Type your answer....a buffer solution is often encountered during the titration of aweak acid. In such a titration, there is a strong base (often sodium hydroxide, as in today’s lab)which is being added to the weak acid. When the strong base reacts with the weak acid, theresult is the conjugate base of the weak acid. It is essential that you not confuse these twobases during the discussion below, and that you write your report so that it is clear which baseyou are talking about. If the pH of the acid solution is monitored during the titration, a pHprofile like the one below can be plotted.

- you need to prepare a pH = 9.20 buffer solution containing NH3 and NH4Cl. if you start with 0.52 M NH4Cl solution, what concentration of NH3 will you need to start with. Kb for NH3 is 1.8x10^-5. Answer in two decimals and with units.In the laboratory, a general chemistry student measured the pH of a 0.453 M aqueous solution of acetic acid to be 2.561. Use the information she obtained to determine the K, for this acid. K,(experiment) =Let's say that you're titrating an acid with a sodium hydroxide solution, and you think you're at the equivalence point (when acid moles = base moles). You (or your partner, I guess) accidentally add an extra drop of base, and the solution immediately turns dark pink. Oh no! Why does the color's intensity change so drastically? a) Sodium Hydroxide is a strong base, so adding any extra amount will dramatically decrease the pH, thus forcing the indicator to turn dark pink. b) Sodium Hydroxide is a strong acid, so adding any extra amount will dramatically decrease the pH, thus forcing the indicator to turn dark pink. c) Sodium Hydroxide is a strong base, so adding any extra amount will dramatically increase the pH, thus forcing the indicator to turn dark pink. d) Sodium Hydroxide is a strong acid, so adding any extra amount will dramatically increase the pH, thus forcing the indicator to turn dark pink.
