Acid Dissociation Constant (Ka): This is the equilibrium constant for the reaction where an acid donates a proton to water. A larger Ka indicates a stronger acid.

Equilibrium Constant (Keq):

This is a measure of the ratio of products to reactants at equilibrium. For acids, this would be [products]/[reactants].

Bronsted-Lowry Acid: This is any substance that can donate a proton or H+ ion.
