Thymol blue is purple in basic solution. So first statement is correct. Second statement is also correct as the first protonation yields orange solution. Third statement is incorrect as purple color is only furnished in basic solution. The final statement is incorrect as thymol never attains green color at any pH.

3. Explain the series of color changes that can occur on thymol blue indicator by the addition of the following solutions. In each case, give the approximate pH of the solution Color change Red to Yellow Yellow to Blue pH range 12 to 2.8 Thymol blue 8.2 to 9.1 a) A few drops of thymol blue are added to 0.1 M aqueous solution of HCl(aq). b) By adding some solid sodium acetate, NaCH,O2 to a solution of (a) e) By...
Using C++ COLOR MIXER- The color red, yellow, and blue are primary colors because they cannot be made by mixing other colors. When you mix 2 primary colors you get the following: When you mix red and blue, you get purple. When you mix red and yellow, you get orange. When you mix blue and yellow, you get green. Write a program to ask the user for 2 primary colors (an error if they are not primary). Then display the...

A coworker claims that Skittles candy contains equal quantities of each color (purple, green, orange, yellow, and red). In other words, 1/5 of all Skittles are purple, 1/5 of all Skittles are green, etc. You, an avid consumer of Skittles, disagree with her claim. Test your coworker's claim at the α=0.01α=0.01 level of significance, using the data shown below from a random sample of 200 Skittles. Which would be correct hypotheses for this test? H0:H0: Red Skittles are cherry flavored;...
