heikkohappoiset
Heikkohappoiset is a Finnish term that translates to "weak acids" in English. In chemistry, a weak acid is a substance that, when dissolved in water, dissociates to a limited extent, releasing hydrogen ions and forming a conjugate base. This dissociation is an equilibrium reaction, meaning that the reaction proceeds in both forward and reverse directions. Unlike strong acids, which dissociate almost completely in water, weak acids only partially ionize, leaving a significant portion of the original acid molecules intact in solution.
The strength of a weak acid is quantified by its acid dissociation constant, denoted as Ka. A
