Concept introduction:
A substance that is expected to change its color in response to a change in the chemical properties of a solution is termed as an indicator. The end point in a titration corresponds to a color change of the solution.
To determine: The color of this solution when thymol blue is added.

- A solution has a pH of 4.5. What would be the color of the solution if each of the following indicators were added? (See Fig. 14-8.) a. methyl orange b. alizarin c. bromcresol green d. phenolphthaleinarrow_forwardWhich of the solutions in Exercise 21 shows the least change in pH upon the addition of acid or base? Explain.arrow_forwardWhich of the indicators in Fig. 14-8 could be used for the titrations in Exercises 57 and 59?arrow_forward
- Compare the percent ionization of the base in Exercise 22a with the percent ionization of the base in Exercise 22d. Explain any differences.arrow_forwardWhen might a pH meter be better than an indicator to determine the end point of an acid-base titration?arrow_forwardCompare the percent dissociation of the acid in Exercise 21a with the percent dissociation of the acid in Exercise 21d. Explain the large difference in percent dissociation of the acid.arrow_forward
