when bromothymol blue was exposed to carbon dioxide what color was the solution? Does this mean you had an acid or a base? why?
Homework Answers
Bromothymol blue on exposed to the solution with added CO2 turns yellow .
It means the solution is acidic.

yellow red green orange purple blue Select the color of the solution using the indicator thymol blue. When you first add indicator to your Na2CO3 solution, the color is blue When you reached the first equivalence point when moles of acid equals moles of base, the color is orange x. When you weren't paying attention and added too much HCl, the color is purple lx. When you really weren't paying attention and reached the second equivalence point, which is NOT...

1.A solution has a pH of 5.5. What would be the color of the solution if each of the following indicators were added? (i) bromophenol blue(ii) bromothymol blue(iii) methyl red (iv) phenolphthalein 2.Calculate the pH at the equivalence point when 50.0 mL of a 0.100 M HN3 acid (a weak monoprotic acid having a Ka = 1.90x10-5) is titrated with 0.100 M NaOH.

10.a. Carbon dioxide produced during cellular respiration can combine with water to form carbonic acid. Bromophenol blue can be used to detect changes in pH. It will remain blue in a basic solution or turn yellow in color in the presence of an acid. you exhaled through a straw into a beaker filled with water and then tested the water with Bromophenol blue, would you predict a change in color, yes or no? REVIEW b. Explain your answer.

Questions 1. a. Carbon dioxide from the atmosphere will dissolve in a NaOH solution if it is left uncovered. How would this affect the molarity of NaOH? b. Why does your titrated solution turn from pink back to colorless after several minutes? 2. What is the difference between an equivalence point and an endpoint? 3. Phenolphthalein actually changes color at around pH 9. Why, then, is it a suitable indicator for the titrations you did today?
