Cationic hydrolysis refers to the hydrolysis of those salts that have strong acid and weak base components.In Cationic hydrolysis the resulting solution is acidic. Potassium carbonate (K2CO3) is a white salt, soluble in water (insoluble in ethanol) which forms a strongly alkaline solution. THe ammonium is acting as an acid (proton donor) hence the ammonia (NH3) is the conjugate base of the acid (ammonium). The pH value for NH4Cl lies between 4.5 and 6 and its pKa value is 9.24, therefore, it is mildly acidic. The reaction is: We are given two of three equilibrium concentrations and asked to find the missing concentration. Some salts formed in neutralization reactions may make the product solutions slightly acidic or slightly basic. It turns out that fish have volatile amines (bases) in their systems, which are neutralized by the acids to yield involatile ammonium salts. When you dissolve ammonium chloride crystals in water (H2O), the ammonium chloride compound decomposes into its component ions: NH4+ and Cl-. Because Kb >> Ka, the solution is basic.
