This property is plotted against the amount of titrant added in a titration chart.
The log of free metal ion concentration in soil increases linearly with an increase in this property. Potential energy is plotted against this property in a diagram that shows regions of passivity and immunity, the Pourbaix diagram. An "optimum" of this property is the range over which an enzyme displays maximum catalytic activity. This property is equal to the negative log of the acid dissociation constant, minus the log of the quotient of the concentration of the weak acid and that of its conjugate base, by the Henderson-Hasselbalch equation. This property is plotted against the amount of titrant added in a titration chart. For 10 points, give this property that equals the negative log of the hydrogen ion concentration in solution, which is seven for pure water.
