Title: {basic strength and pkb}
Post by: Ayushmaan on October 30, 2017, 11:35:21 AM
How are basic strength and pkb value related???
Does higher pkb mean lower basic strength?

Show the mathematical relationship between Kb and pKb, and the answer may suggest itself to you.

I think OP was wanting to know the relationship between Kb (pKb) and [OH-]. In which case, still do as Babcock suggests: set up the standard mathematical relationship which describes [OH-] and Kb.

The definition of pKb is that pKb = -log10Kb.

@OP, What does this imply about base strength?
