How can one strong acid be stronger than another if they both fully ionize and acid stregnth is a measure of how much an acid ionizes in water
Accepted Answer
Strong acids are Bronsted-Lowry acids that fully dissociate in water. The strength of an acid is a measure of its ability to donate a proton (H+ ion). The higher the concentration of H+ ions in solution, the stronger the acid. Even though strong acids fully ionize, they can have different strengths. This is because the equilibrium constant for the dissociation reaction is different for each acid. The equilibrium constant is a measure of the extent to which the acid dissociates. A higher equilibrium constant means that the acid dissociates more completely, resulting in a higher concentration of H+ ions and a stronger acid.
