Study on the Salt Effect of Aliphatic Acids in Aqueous Salt Solutions

Based on the molecular topological theory,we introduce a new topological index Y and use it to study for salt effect constant k s of aliphatic acids in the salt solution.Our research indicates that for the above salt effect constant k s,there is a good linear relation between Y and k s and the related equation is eslablished.For this new method the calculation is convenient and the result is accurate.It has clear physical significane.
