Question
Chapter 9, Problem 95P
Interpretation Introduction
Interpretation:
The correct representation of buffer solution with a small amount of strong acid should be determined.
Concept Introduction:
A buffer solution is a mixture of weak acid or base with its conjugate base that resists any change in pH of the solution even after the addition of a little amount of acid or base. Thus there is no change in pH of buffer solution even after the addition of acid or base to the solution. This is because weak acid reacts with excess ions to form its conjugate base and water whereas the conjugate base reacts with excess ions to form a respective weak acid.

- What is the pH of a solution obtained by adding 13.0 g of NaOH to 795 mL of a 0.200 M solution of Sr(OH)2? Assume no volume change after NaOH is added.arrow_forwardMethyl orange, HMO, is a common acid-base indicator. In solution it ionizes according to the equation: HMOaqH+aq+MO-aqredyellow If methyl orange is added to distilled water, the solution turns yellow. If 1 drop or two of 6 M HCl is added to the yellow solution, it turns red. If to that solution one adds a few drops of 6 M NaOH, the color reverts to yellow. a. Why does adding 6 M HCl to the yellow solution of methyl orange tend to cause the color to change to red? Note that in solution HCl exists as H+ and Cl- ions. b. Why does adding 6 M NaOH to the red solution tend to make it turn back to yellow? Note that in solution NaOH exists as Na+ and OH- ions.

Be sure to fully justify your answer. i You prepare a 1.0-L solution of HA. You then take a 200-mL sample of this solution and place it into a separate container.
