Second deprotonation

Postby Maayan Epstein 14B » Tue Jan 22, 2019 11:07 pm

Do we need to know second deprotonation for tomorrow's test?
Some of the homework problems for chapter 12 mention it (i.e. 6th edition 12.81)

No, I do not think he will be testing us on this concept even though it was lightly touched upon in our Chapter 12 homework.

There really isn't much to it. Just know that the K values decrease significantly after each deprotonation so for most acids we only consider the 1st deprotonation (H2SO4 is the only excpetion according to the textbook where the first and second deportonations must be considered and two ice tables would be needed if you were asked to find the pH).

I would assume not just because it wasn’t really covered in lecture or discussion sections.
