question about strong and weak acid
« on: April 16, 2016, 11:31:21 AM »
As far as I know, strong acid means it can ionize completely. In other words, weak acid can't.
But however will their amount of product be the same? And why is there a difference in rate of reaction?
Take HCl and ethanoic acid as example.
HCl :rarrow:H++Cl-
H+:Cl+= 1:1
CH3COOH :rarrow:CH3COO-+H+
CH3COO-:H+=1:1
Is that means that had the same concentration of H+?

Dissociation of ethanoic acid is an equilibrium process. That means - in 1 M acid dissociates about
1 % molecules, in 10-3 M acid - about 13 % of molecules, and in 10-6 M - about 70 % of molecules.
