A chemistry graduate student is given 500. mL of a 0.60M nitrous acid (HNO,) solution. Nitrous acid is a weak acid with K=4.5 x 10 -4 What mass of KNO, should the student dissolve in the HNO, solution to turn it into a buffer with pH = 3.88? You may assume that the volume of the solution doesn't change when the KNO, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits.

Sketch the titration curve for a weak acid titrated by a strong base. When performing calculations concerning weak acidstrong base titrations, the general two-slep procedure is to solve a stoichiometry problem first, then to solve an equilibrium problem to determine the pH. What reaction takes place in the stoichiometry part of the problem? What is assumed about this reaction? At the various points in your titration curve, list the major species present after the strong base (NaOH, for example) reacts to completion with the weak acid, HA. What equilibrium problem would you solve at the various points in your titration curve to calculate the pH? Why is pH 7.0 at the equivalence point of a weak acid-strong base titration? Does the pH at the halfway point to equivalence have to be less than 7.0? What does the pH at the halfway point equal? Compare and contrast the titration curves for a strong acidstrong base titration and a weak acidstrong base titration.
A monoprotic organic acid that has a molar mass of 176.1 g/mol is synthesized. Unfortunately, the acid produced is not completely pure. In addition, it is not soluble in water. A chemist weighs a 1.8451-g sample of the impure acid and adds it to 100.0 mL of 0.1050 M NaOH. The acid is soluble in the NaOH solution and reacts to consume most of the NaOH. The amount of excess NaOH is determined by titration: It takes 3.28 mL of 0.0970 M HCl to neutralize the excess NaOH. What is the purity of the original acid, in percent?
What is meant by the capacity of a buffer? Describe a buffer with low capacity and the same buffer with greater capacity.
The three flasks shown below depict the titration of an aqueous NaOH solution with HCl at different points.
