pKb Definition in Chemistry - ThoughtCo
WebJul 17, 2024 · pK b is the negative base-10 logarithm of the base dissociation constant (K b) of a solution. It is used to determine the strength of a base or alkaline solution. pKb = -log 10 K b The lower the pK b value, the stronger the base. WebJan 30, 2024 · For a given general chemical equation: a A + b B ⇌ c C + d D the Q equation is written by multiplying the activities (which are approximated by concentrations) for the species of the products and dividing by the activities of the reactants. WebJul 1, 2024 · The equilibrium constant value is the ratio of the concentrations of the products over the reactants. This means that we can use the value of K to predict whether there are more products or reactants at equilibrium for a given reaction.
