As the pH of a substance rises from 7, it turns from a weak base to a strong base. A strong acid such as HCl, when mixed with water, will separate into molecules of hydrogen ions and chloride ions. That is called dissociation. Strong acids dissociate more completely than weak acids, ...
PurificationElectrolytesManganese inorganic compoundsSulfuric acidPolymersA method is described for the removal of acid and sulphates from finely milled electrolytic manganese dioxide (EMD) by the use of a strong or weak-base anion-exchange resin in a one-step operation. The method has the advantage...

A model is developed to predict protein retention and resolution in mixed-bed columns containing a mixture of a small-pore weak base resin and a large-pore strong base resin. Using amine buffers, the weak base resin generates smooth pH gradients when the column is subjected to pH steps, whil...
