Determine the volume of NaOH at the equivalence point, volume of NaOH added at half the equivalence point, the pH at half the equivalence point, the pKa and the Ka of acetic acid. (0.2pts) Volume of NaOH to reach half-equivalence point. (0.2pts) Volume of NaOH to reach equivalence point: (0.2pts) pH at the half equivalence point: (0.2pts) Experimental pKa of acetic acid: (0.2pts) Experimental Ka of acetic acid: 2. Calculate the dissociation constant of acetic acid using the data from Step 8. The pH you recorded for this solution in Step 8 was: 2.33 (0.25pts) Determine the acetate ion concentration, [A-], at equilibrium. (0.25pts) Determine the acetic acid concentration, [HA], at equilibrium. (0.25pts) Determine the experimental value of Ka of acetic acid. (0.25pts) Show your calculation of [H ] from the pH and calculation of the Ka value. (Please upload PDF only) Maximum size for new files20.00MB

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
