1. THE SHIFTING OF AN EQUILIBRIUM: THE COMMON ION EFFECT Weak Acids and Weak Bases • • • Let us now examine weak acids and weak bases from an equilibrium point of view. In a solution of the weak acid, HC2H3O2, the following equilibrium exists: HC2H3O2 (aq) H+ (aq) + C2H3O2 (aq) To 3 mL of 0.10 M HC2H3O2 add a drop of methyl orange, then add 1 M NaC2H3O2 a few drops at a time, with mixing. Explain your observations in terms of the equilibrium equation and the common ion effect. Write the equilibrium equation and explain your observations in terms of the equilibrium equation and the common ion effect in your notebook.

+ pH Changes in Buffers When a solution contains a weak acid and its conjugate base or a weak base and its conjugate acid, it will be a buffer solution. Buffers resist change in pH following the addition of acid or base. A buffer solution prepared from a weak acid (HA) and its conjugate base (A) is represented as HA (aq) → H¹ (aq) + A (aq) The buffer will follow Le Châtelier's principle. If acid is added, the reaction shifts to consume the added H+, forming more HA. When base is added, the base will react with H+, reducing its concentration. The reaction then shifts to replace H+ through the dissociation of HA into H+ and A™. In both instances. [H] tends to remain constant. The pH of a buffer is calculated by using the Henderson-Hasselbalch equation: A] pH =pK₂ +log HA ▼ Part A pH = What is the pH of a buffer prepared by adding 0.607 mol of the weak acid HA to 0.507 mol of NaA in 2.00 L of solution?

Buffer capacity is a measure of a buffer solution's resistance to changes in pH as strong acid or base is added. Suppose that you have 145 mL of a buffer that is 0.300 M in both acetic acid (CH₂COOH) and its conjugate base (CH3COO-). Calculate the maximum volume of 0.170M HCl that can be added to the buffer before its buffering capacity is lost. volume: esc ! 1 ← 2 #3 с $ 4 G Search or type URL 27 20 % MacBook Pro 5 ^ 6 & 7 +00 8 ( 9 ) mL 0 1
