WitrynaPartitioning Behavior of Organic Acids and Bases pH dependence of solubility speciation Solubility is the equilibrium partitioning of a compound between the pure liquid phase and water. The solubility and activity coefficient of HA (the neutral form) depends on its size, polarity, and H-bonding ability. The intrinisic WitrynaSolubility is the measure of the maximum amount of solute that can be dissolved in a given quantity of solvent. Temperature, pressure, and molecular polarity are some of the important factors that affect solubility. Solubility equilibrium is established when the dissolution and precipitation of a solute species occur at equal rates.

WitrynaThe stability of the conjugate base, can also affect the strength of the acid. The more stable the conjugate base, the more likely the asset is to donate a proton. So if you think about that for HA, the conjugate base is A minus. And the more stable A minus is, the more likely HA will donate a proton in solution.
