SOLVED:A buffer contains a weak acid, HX, and its conjugate base. The weak acid has a p Ka of 4.5, and the buffer has a pH of 4.3 . Without doing a calculation, predict whether [HX]=[X^-] [HX]>[X^-], or [HX]<[X^-] . Explain. [ Section 17.2]

SOLVED: A buffer is a mixture of a weak acid and its conjugate base or a weak base and its conjugateacid. A buffer’s function is to absorb acids (H or H3O ions) or bases (OH– ions) so that the pHof the system changes very, very little.In many systems, buffers are critical. Blood plasma, a natural example in humans, is abicarbonate buffer that keeps the pH of blood between 7.2 and 7.6.By design, a buffer is an equilibrium system. For example, a buffer can be prepared with nitrousacid, HNO2. The

SOLVED:Using eq: 7:2.3 BC = 1 1 WA CBcalculate the buffer capacity (BC) of your buffer solution before and after dilution with water; and enter the values obtained below: Remember that before dilution the water volume in the flask was 25 mL: After dilution, the volume was 35 mL. The number of moles of weak acid and conjugate base will depend on the amounts added to the flask: Your weak acid's molar mass is 234 and that of the conjugate base is 256.
