Web23 apr. 2024 · Explanation: An ion product constant is basically the same thing as an equilibrium constant. This is described mathematically as follows: For the following reaction: aA +bB ⇌ cC +dD. K (i.e. the equilibrium constant) = [C]c[D]d [A]a[B]b. Note that if a species in the reaction has a coefficient, you raise it to the power of that coefficient. Web24 jan. 2024 · Ans: The Ionic Product of Water, \ ( { {\rm {K}}_ {\rm {w}}}\) is the equilibrium constant for the reaction in which water undergoes an acid-base reaction.
