Ignoring Deprotonations

Postby Nathan Mariano 2G » Wed Jan 23, 2019 10:02 pm

While doing polyprotic acids and base calculations, what approximation justifies ignoring the second deprotonations?

In the textbook, it says that if Ka2 is less than Ka1/1000, then you can ignore the second deprotonation.

Hope this helps!
