Equilibrium weak and strong acids answer key

WebThe generic equilibrium constant expression for a weak acid is written as follows. If the acid is strong enough to ignore the dissociation of water, the H 3 O + ion and A - ion concentrations in this solution are about equal. … WebJul 21, 2024 · The pKa is derived from the equilibrium constant for the acid’s dissociation reaction, Ka, and uses a logarithmic scale to allow the pKa values to span wide ranges. pKa = –log Ka. The lower the pKa value of an acid, the stronger the acid. The higher the pKa value, the weaker the acid. Very strong acids have pKa values of less than zero ...
