An acid with higher Acid dissociation constant| value dominates the chemical reaction. It serves as a better contributor of protons (). A comparison between the  and Base dissociation constant| indicates the acid–base property of the resulting solution by which:
# The solution is acidic if . It contains a greater concentration of  ions than concentration of  ions due more extensive of cation hydrolysis compared to that of anion hydrolysis.
# The solution is alkali if . Anions hydrolyze more than cations, causing an exceeding concentration of  ions.
# The solution is expected to be neutral only when .
Other possible factors that could vary pH level of a solution are the relevant equilibrium constants and the additional amounts of any base or acid.
For example, in ammonium chloride solution,  is the main influence for acidic solution. It has greater  value compared to that of water molecules;  of  is , and  of  is . This ensures its deprotonation when reacting with water, and is responsible for the pH below 7 at room temperature.  will have no affinity for  nor tendency to hydrolyze, as its  value is very low ( of  is ).
Hydrolysis of ammonium at room temperature produces:
