Percent ionization of weak acids
« on: October 12, 2008, 08:26:32 PM »
What is the molar concentration of acetic acid at equilibrium in an acetic acid solution that is 1.1% ionized?

What percentage of acetic acid do you have?

i dont know all it gave me in the question was that it was 1.1% ionized

And that's enough. Do you know how to calculate percent ionizoation given acid concentration? You have just to reverse the process.

Note, that 1.1% percent ionization means that you can use the simplest formula for the weak acid pH calculation, the one that works if ionization is below 5%.

Its quite simple. Rearrange the Ostwald dilution law and put in your ionization degree as a number, not as a percent.
