pKb
pKb is a numerical value used in chemistry to measure how strongly a base (a substance that can accept protons) reacts with acids. It is the negative logarithm (base 10) of the base's dissociation constant (Kb), which indicates the extent to which the base releases hydroxide ions in solution. A lower pKb means the base is stronger and more willing to accept protons, while a higher pKb indicates a weaker base. pKb helps chemists compare the strengths of different bases systematically.
