% dissociation

[Jasleen Kahlon]

Can someone please explain what % dissociation means and how it is calculated?

[Myka G 1l]

Percent dissociation is the amount of H+ ions produced by an acid in solution divided by the amount of unreacted acid [HA].

[Venus_Hagan 2L]

percent dissociation is how much of the acid separated into its conjugate base and a proton compared to the original amount of acid or how much of the base separated into its conjugate acid and OH- compared to the original amount of base. You can calculate it by putting either the concentration of the conj acid/base over the original concentration of the acid/base

sorry correction not over the original concentration, its over the concentration of unreacted acid/ base

% disassociation is a measurement of how much an acid has "dissociated" or disconnected into its constituent parts in a solution.

take for example iodic acid


In the solution of H₂O , the iodic acid will naturally come apart (based on its K_a) into its constituent base IO₃^- and H₃O⁺ .

Once there are cations floating around, they act acidically. But importantly, when an acid breaks into parts, that is it losing association: dissociating.

The way that we calculate % dissociation is by dividing the concentration of H₃O⁺ ions over the initial concentration of the acid (in our case HIO₃)

Calculate the amount of H+ and divide by orginal amount of acid then multiply by 100
