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…

Caculate the pH of a solution prepared by mixing 84.7 mL of a 0.25 M aqueous aniline solution (C6H5NH2, Kb = 4.3 x 10-10) with 100. mL of a 0.11 M aqueous nitric acid solution. Your pH should be reported to two places past the decimal point.
In the experiment, we used titration to determine the total acid content ofsamples, which we reported in terms of molarity. Reporting acidity through pHmeasurements is quite different, in that we can only measure the amount of theacid in its ionized form. You were tasked to investigate a clear aqueous solutionof an unknown monoprotic acid. You decided to use two methods togather data.Method 1 – TITRATION: A 10. mL aliquot of the sample was diluted with 25 mLdistilled water. Two drops of phenolphthalein were added and then it was titrated3.54 mL of 0.048 M standardized NaOH to the endpoint.Method 2 – pH STRIP: You took 1 mL of the sample and used a pH strip toestimate the pH, which turned out to be around 3.3. Another 1 mL of the samplewas diluted with 9 mL of water. The pH was taken again and is now around 3.8.a) Calculate the molarity of the acid using the titration data.b) If we assume that the titrated unknown is a strong acid, predict thepH of the sample.c) Using pH strip results,…
