iii. Starting from the fully protonated form of L-Glutamic acid, determine the pH of the titration solution if 22.00 mL of 0.4000M of NaOH was added to 15.00mL L-Glutamic acid solution with a concentration of 0.8000M. Show work and report your values with the correct numbers of significant figures and unit. No credit will be given for this part if no work is shown. Extra space is provided on the next page.

Using the 1 mM solution of p-nitrophenol (PNP) provided, create a series of dilutions. You will make 10, 25, 50, 75, and 100 μM solutions. In making these solutions, use 1x reaction buffer (0.2 M Tris, pH 8.0; 5 mM MgCl2) as the diluent. You will need 1 mL of each of these solutions

A mixture of benzoic acid and naphthalene was separated by a liquid-liquid extraction by converting the benzoic acid into its water soluble sodium salt. How can the benzoic acid be recovered after the two layers were separated? Group of answer choices Acidify the aqueous solution containing the sodium benzoate to pH 2 and filter. Add an excess of 1.0 M NaOH to the aqueous solution containing the sodium benzoate and filter. Add diethyl ether to the aqueous solution containing the sodium benzoate and filter. Dry the the aqueous solution containing the sodium benzoate with anhydrous sodium sulfate and filter.
