The acid dissociation constant is the equilibrium constant of the dissociation reaction of an acid and is denoted by K a. This equilibrium constant is a quantitative measure of the strength of an acid in a solution. K a is commonly expressed in units of mol/L.

pKa, Ka, and Acid Strength - YouTube

WebI know as a fact that HCl is a stronger acid than H3O+, but I want to know the reason behind it. The definition of an acid is a substance which dissociates to give H3O+ ions. In that case H3O+ should be the strongest acid available because it does not even need to dissociate it give itself!! acid-base. equilibrium. WebFor example, the Ka constant for acetic acid (CH 3 COOH) is 0.0000158 (= 10-4.8), but the pKa constant is 4.8, which is a simpler expression. In addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid. how to sort by controversial on pc reddit
