The acid–base indicator bromcresol green is a weak acid.The yellow acid and blue base forms of the indicator arepresent in equal concentrations in a solution when the pHis 4.68. What is the pKa for bromcresol green?
The indicator methyl red has a pKHIn = 4.95. It changes from red to yellow over the pH range from 4.4 to 6.2. If the indicator is placed in a colourless buffer solution of pH = 4.55, what percent of the indicator will be present in the acid form, HIn?

The phenolphthalein pH indicator is clear and colorless in an acidic solution, but it turns a pink in a basic solution. Knowing this, you examine two clear and colorless solutions. One, you are told is acidic and the other is basic. Furthermore, you are told that the acidic solution contains phenolphthalein. So which is which? You don’t know because both solutions are colorless. To find out, you add a drop of Solution 1 to Solution 2. A pink color appears for a moment, but then disappears. This tells you that Select one: a. you now need to try adding Solution 2 to Solution 1. b. Solution 2 is acidic. c. Solution 1 is acidic. d. both solutions are now neutralized.
How to write the methodology? I have a practical of the MEASUREMENT USING PH METER, I don't know how to write the methodology. Here is the introduction: A pH meter is an electronic device mainly used for qualitative measurement, for thedetermination of acid and the basic value of a solution. Generally, it measures thehydrogen ion concentration/activity [H+] in a solution. It is denoted as:pH = - log10 [H+]In a pure water solution, the concentration of [H+] and [OH-] ions, respectively, rangefrom 1.0 x 10-1 M to 1.0 x 10-14 M. When [H+] is equal to [OH-] as when pure waterdissociates, the hydrogen ion concentration of pure water is equal to 1.0 x 10-7 M orpH = 7.00, defined as a neutral solution at 25°C, to be of temperaturedependent/endothermic dissociation.[H+] = [OH-] = 1.0 x 10-7 MWhen an ionic or polar substance is dissolved in water, it may change the relativenumbers of H+ and OH-. The higher the pH number, the lower the hydrogen ion concentration, and vice versa. Solution with an…
The indicator ethyl red has Kₐ=3.8X10⁻⁶. Over what ap-proximate pH range does it change color?
An acid-base indicator is usually a weak acid with a characteristic color in the protonated and deprotonated forms. In this assignment, you will monitor the color of an acetic acid solution containing Bromocresol Green as an indicator, as the pH is changed and then you will estimate the ionization constant, Ka, for the indicator. This is a lab I have to do. I have it done I just need an introduction to it. It was on Ionization Constants of Weak Acids Example of first question. Rememember just need. wirtten introduction. Thank you!
