This dissociation property is represented by a sigmoidally shaped curve i.e. one curved in two different directions like the letter "S" on a cartesian coordinate plot of the negative logarithm (log) of metal ion concentration versus the negative logarithm (log) of hydrogen ion concentration for otherwise known as a pM-pH diagram). …
