Question 12.55 (Sixth Edition)

[Steve Magana 2I]

Question: Calculate the pH, pOH, and percentage deprotonation of each of the following aqueous solutions: (a) 0.20 m CH3COOH(aq); (b) 0.20 m CCl3COOH(aq); (c) 0.20 m HCOOH(aq). (d) Explain any differences in pH on the basis of molecular structure.

For a question like this, how would you find the percentage deprotonation? Thank you!

You would first need to do an ICE table to find x, which will tell you your CH3CO2 concentration (for example in part a). After finding this, you should divide it by your initial concentration of CH3COOH (0.20 M in part a) to get your percentage deprotonation. For what percentage deprotonation is, I found this earlier link that might help! viewtopic.php?t=24737
