3. Using Equation 18-5 and the pKIn value you found, determine the ratio [In-]/[HIn] at the pH in the middle of the range you studied (i. e., pH = 6.0 for bromocresol purple, pH = 7.0 for bromothymol blue, and pH = 7.7 for phenol red). Show how you accomplished this. Draw a conclusion about the relative concentrations of In- and HIn at pH values very close to the pKIn of the indicator.

Explanation:

[In-]/ [HIn] = [KIn]/ [H3O+]

Use the  values of  PkIN = 7.1,

KIN=8.14E-8, and

[H3O+] = 10E-7

To plug them in as follows:

(8.14E-8)/ (10E-7) = 0814, thus shows a  very close  ratio 1 to 1

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
