According to the Henderson–Hasselbalch equation, when the pH of a solution of histidine is 1.85, what is the ratio of the carboxylic acid form of the molecule to its conjugate base (the carboxylate form)? [For practice, either use Marvin Sketch or a piece of paper to draw the acid and conjugate base.] 1 or 4?

The Henderson-Hasselbalch equation relates the pH of a buffer solution to the pKa of its conjugate acid and the ratio of the concentrations of the conjugate base and acid. The equation is important in laboratory work that makes use of buffered solutions, in industrial processes where pH needs to be controlled, and in medicine, where understanding the Henderson-Hasselbalch equation is critical for the control of blood pH. Part A As a technician in a large pharmaceutical research firm, you need...

10. Looking at the Henderson-Hasselbalch equation, what would be required to use the ratio as "[HA][A]" instead of "Ay[HA]" in the log argument? In other words, manipulate the equation so that the ratio in the log part is inverted. HINT! Remember "properties of logs" and what it means to invert a ratio. I want you to rewrite the Henderson-Hasselbalch equation here so that it is correct but uses "[HA][A]" instead of “[A][HA]" in the log argument, the equation should look...

1. Calculation: Using the Henderson-Hasselbalch equation, explain mathematically why a solution is at a pH below the pKa for an acid that more than 50% of the molecules have the proton on (not off). 2. Calculation: If you have a pH of 5.5 for a weak acid with a pKa of 4.76, then is there more A- or more HA in the solution? Explain why in words using your knowledge of positive or negative log numbers.
