The Acid Constants for Some Acids at 25°C.
Above is a table of Ka values which define the extent to which an acid will donate its proton to water. The values of the constant is defined by the equation:
The Base Constants for Some Bases at 25°C.
Above is a table of Kb values which define the extent to which an base will accept a proton from water. The value of the constant, similar to above, is defined as:
