Interpretation:
The equation for reaction when
Concept Introduction:
On addition of limited amount of an acid or base, if a solution does not change the pH, it is known as buffer solution. For example: aqueous solution of weak acid and its conjugate base. This property of buffer to resist the pH is known as buffer action.
For an effective buffer, the value of pH is equal to the

- 8-53 Write equations to show what happens when, to a buffer solution containing equimolar amounts of CH3COOH and CH3COO-, we add: (a) H3O (b) OH-arrow_forward8-13 Define (a) an Arrhenius acid and (b) an Arrhenius base.arrow_forwardYou are asked to calculate the H+ concentration in a solution of NaOH(aq). Because sodium hydroxide is a base, can we say there is no H+. since having H+ would imply that the solution is acidic?arrow_forward
- 8-96 Suppose you want to make a CH3COOH/CH3COO- buffer solution with a pH of 5.60. The acetic acid concentration is to be 0.10 M. What should the acetate ion concentration be?arrow_forwardHow is acid strength related to the value of Ka? What is the difference between strong acids and weak acids (see Table 13-1)? As the strength of an acid increases, what happens to the strength of the conjugate base? How is base strength related to the value of Kb? As the strength of a base increases, what happens to the strength of the conjugate acid?arrow_forwardUsing the diagrams shown in Problem 10-37, which of the four acids is the weakest acid?arrow_forward
- Briefly describe two methods for determining Ka for a weak acid.arrow_forward8-15 Write an equation for the reaction that takes place when each base is added to water. (a) LiOH (b) (CH3)2NH (c) Sr(OH)2 (d) CH3CH2NH2arrow_forwardExplain why the pH does not change significantly when a small amount of an acid or a base is added to a solution that contains equal amounts of the base NH3 and a salt of its conjugate acid NH4CI.arrow_forward
