(a) Interpretation: To determine the equilibrium concentration of HI and I- in 1.0 M HI. Concept introduction: The dissociation constant of an acid is denoted by K a and is also known as acidity constant or the acid-ionization constant refers to the quantitative measure that determines the strength of the given acid. It is also known to be the equilibrium constant for the chemical reactions which are known as dissociation reactions in the context of base-acid reactions.
