Write the Henderson-Hasselbalch equation for a propanoic acid solution (CH₂CH₂CO₂H, pKa [HA] pH = = 4.352 || pH = 4.874 Answer Bank [A] + log Using the equation to calculate the quotient [A¯]/[HA] at three different pH values. [A-] [HA] [A-] [HA] - o = pka pH = 4.874).
In this activity you will use the virtual lab to determine the concentration of a strong monoprotic acid. To do this, you can perform a titration using NaOH and phenolphthalein found in the virtual lab. (Note: The concentration of the acid is between 0.025M and 2.5M so you will need to dilute the NaOH solution so that the volume to reach the endpoint is between 10 and 50 mL). Once you have determined the concentration of the acid, please enter your answer into a form at the bottom of this page. Unknown acid: 10 ml 0.15 ml of phenolphthalein 0.60 ml of NaOH

Time to purify biochemisfunase! To do this, you’ll need to make MORE buffers. One of the buffers that you need to make requires 150 mM Tris (pH 8), 250 mM sodium chloride (NaCl) and 2 mM dithiothreitol (DTT, a reducing agent that prevents the formation of disulfide bonds in proteins). Your jolly postdoc friend wants you first to make 500 ml of a1.0M Tris stock solution before making the buffer. Describe how you would make this stock solution, and show all calculations.
