Hydrolysis and Speciation, not making sense.
« on: April 28, 2012, 03:38:56 AM »
Hi
I am having trouble understanding the diagram on slide 5 on the attached pdf, and the maths on slide 4 for it.

I do not understand the relationship between, pH and Ka or Pka whatever the maths is trying to show.

Its mostly the equations shown.

Thankyou, pleae help because I am so stuck.

Red is a fraction of the protonated acetic acid (CH3COOH), blue is the fraction of the conjugate base (CH3COO-). The higher the pH the higher the fraction of the conjugate base (the more acid becomes neutralized), the lower the pH, the more acid is in the protonated form.
