decompose salt of weak acid

In this case both the cation and anion undergo hydrolysis to the same or different extents. The resulting solution may be neutral, acidic or basic depending upon the relative strengths of acids and bases. The hydrolysis may be written as: ..

In this case both the cation and anion undergo hydrolysis to the same or different extents. The resulting solution may be neutral, acidic or basic depending upon the relative strengths of acids and bases. The hydrolysis may be written as: Some common examples are CH 3 COONH 4 , ..

Here, the anion (A - ) is a stronger base than OH - , hence it undergoes hydrolysis to give free OH - ions. Therefore the resulting solution will be basic in character having pH greater than 7. For example Other examples of this type of salts are CH 3 COONa, Na 2 CO 3 , Na 3 PO 4 , et..

Here, cation B + undergoes hydrolysis to give free H + ions. Therefore the resulting solution will be acidic in character having pH less than 7. For example, Other examples of this type of salts are NH 4 Cl, CuSO 4 , AlCl 3 , etc. The aqueous solution of a salt of stro..

An acid salt is formed when a strong acid combines with a weak base. It liberates hydrogen or hydronium ions, it exhibits some acidic properties. Hence it behaves like an acid and has a pH of less than ..

A base that dissociates in water only partially is known as a weak base. Example: Examples of Bases Strong Weak Sodium hydroxide: NaOH Magnesium hydroxide: Mg(OH) 2 Potassium hydroxide: KOH Calcium hydroxide: Ca(OH) 2 Ammonium hydroxide: NH 4 OH ..

An acid that dissociates only partially when dissolved in water, is classified as a weak acid. Most of the molecules remain in solution in molecular form itself in such acid. Examples are: acetic acid, formic acid, carbonic acid..

Summary - Acidic substances generate H + ions in the medium, while basic ones liberate OH - ions in the medium Certain dyes are used as indicators to detect the presence of acids and bases Strength of an acid depends on the concentration of hydronium ions present in a ..

The heat of neutralization of a weak acid or a weak base is less than -57.1 kJ and is also different for different weak acids or bases. For example for acetic acid the enthalpy of neutralization is -54.9 kJ. This can be explained as follo..

Summary - Strength of an acid depends on the concentration of hydronium ions present in a solution. Greater the numbers of hydronium ions present, greater is the strength of the acid. A strong acid dissociates completely in water. Example: Hydrochloric acid A ..
