The ALPHA value of Buffered Solutions
« on: July 27, 2007, 03:24:24 AM »
The alpha value is represented as

a0 = [concentration of undissociated acid] / [total concentration of solution]

I can derive and manipulate this accordingly.

My question is, what use does such a value or function have in our chemical world?

Do you mean - degree of dissociation

I suppose you mean dissociation fraction - see http://www.chembuddy.com/?left=pH-calculation&right=introduction-acid-base-equilibrium

See also http://www.chembuddy.com/?left=pH-calculation&right=general-pH-calculation - dissociation fraction is routinely used to check if the so called 5% rule holds.
