ANSWER:Solution 54P
Step 1 of 4:
Here, for the given compounds, we are asked to draw the form in which compounds will predominate at pH = 3, pH = 6, pH = 10, and pH = 14. This can be done using the Henderson–Hasselbalch equation.
Henderson–Hasselbalch equation is the equation that relates pKa of the acid and the pH of the solution, which is derived to calculate precisely how much of the compound will be in its acidic form and how much will be in its basic form at a particular pH.
The equation is as follows :
pKa = pH +
When, pKa > pH, acid form predominates, which means solution is more acidic.
When pKa < pH, base form predominates, which means solution is more basic.
