The relationship between Log P and Log D differs for ionizable and non-ionizable compounds. Non-ionizable compounds have a consistent Log P value throughout the pH range. However, for ionizable compounds, the value of Log D considers the partitioning of both ionized and non-ionized forms. This implies that the pH of the solution can impact the extent to which ionizable compounds are ionized, and therefore their Log D value.What is the molecule's logarithmic value of D in the negative form?
