The two numbers that predict which way chemistry's most important argument will go.
means pKa measures acid strength (lower = meaner proton donor); pKb measures base strength (lower = greedier for protons). They're inverse twins: pKa + pKb = 14 in water.
from Derived from Ka and Kb, the equilibrium constants for acid and base dissociation. The 'p' prefix means negative logarithm—Søren Sørensen's 1909 shorthand for pH, repurposed to tame unwieldy exponents into readable numbers.
