QUESTION:

An aqueous solution of a 0.10 M monoprotic acid HA has an osmotic pressure of 3.22 atm at 25°C. What is the percent ionization of the acid at this concentration?

ANSWER:

Step 1 of 4

We need to find the percent ionization of the monoprotic acid HA under the given conditions.

The osmotic pressure is the pressure required to stop osmosis, which is the selective passage of solvent molecules from a dilute solution to a more concentrated solution. The osmotic pressure is given by

where is the molarity of the solution

is the gas constant

is the absolute temperature.
