Two students were asked to determine the Kb of an unknown base. They were given a bottle with a solution in it. The bottle was labeled aqueous solution of a monoprotic strong acid. They were also given a pH meter, a buret, and an appropriate indicator. They reported the following data: volume of acid required for neutralization = 21.0 mL pH after 7.00 mL of strong acid added = 8.95 Use the students' data to determme the Kb of the unknown base.
Explain why an acid-base indicator changes color over a range of pH values rather than at a specific pH.
There is a buffer system in blood H2PO4 HPO42 that helps keep the blood pH at 7.40. (K aH2PO4 =6.2108). (a) Calculate the[ H2PO4 ]/[ HPO42 ] ratio at the normal pH of blood. (b) What percentage of the HPO42 ions are converted to H2PO4 when the pH is 7.00? (c) What percentage of the H2PO4ions are converted to HPO42 when the pH is 8.00?
A chemist wishes to manually calculate a derivative; the change in pH divided by the change in volume (∆pH/∆vol). The uncertainty in the pH measurements (epH) is 0.01 pH units. The uncertainty in the volume measurements(evol) is 0.03 mL. What is the expected uncertainty of the result if the chemist tries to make a measurement with a pH change of 0.30 and a volume change of 0.15 mL?

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,…
