X 15. To make the calibration curves, you need the indicator to be essentially one color or the other. To produce the yellow form of the indicator, what should you add? b. acid, H+ (aq) c. salt, NaCl (s) d. gas, Ar (g) a. base, OH (aq) X 16. How do the values of K compare when the solution is orange as in #14 or yellow as in #15? c. Korange>Kyellow a. They are the same b. Korange

Question

Not sure about how to answer any of these 3 questions. I guessed on the first one. Would greatly appreciate someone showing their work and more of an explanation for 15 and 16. Thankyou.

Consider the reaction below and Figure 1 for the following 3 questions. ** A particular indicator that has a red form and a yellow form, depending on the pH. pH = -log [H+] Hind (aq) =H* (aq) + Ind (aq) (red) (yellow) ✓ 14. You have an "orangish" solution of the indicator that you analyze in the spectrometer. Ared = 0.116 for the red form, Ayellow = 0.295 for the yellow form and the pH is 3.88. What is K for this reaction? a. 7.21x10-5 b. 1.36x10-5 1.32x10-4 d. 1.28x10-3 X 15. To make the calibration curves, you need the indicator to be essentially one color or the other. To produce the yellow form of the indicator, what should you add? a. base, OH (aq) b. acid, H+ (aq) c. salt, NaCl (s) d. gas, Ar (g) X 16. How do the values of K compare when the solution is orange as in #14 or yellow as in #15? b. Korange <Kyellow C. Korange>Kyellow a. They are the same d. Korange= -Kyellow
