The acid ionization constant is the equilibrium constant of the dissociation reaction of an acid and is denoted by Ka. This equilibrium constant is a quantitative measure of the strength of an acid in a solution. If Ka is small (pKa is large), little dissociation has occurred, so the acid is weak.
So correct answer is smaller the acid ionization constant is, less the acid ionizes and weaker the acid.

Question 5 (4 points) Definitely don't get this in your eyes! H2SO4 is a strong acid while H, PO, is a weak acid. Which of the following reasons correctly explains why that's true? There are between 1 and 4 correct answers. la H2SO, is a stronger acid than H3PO4 because H,SOhas fewer protons to lose. H2SO, is a stronger acid than H, PO, because the conjugate base, HSOA. is less stable than the conjugate base, H PO H,SOis a stronger...
