salt of a weak base

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 , (NH 4 ) 2 ..

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..

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 strong acid an..

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 etc. ..

A base that dissociates only partially into ions in aqueous medium is called a weak base. It behaves as a weak electrolyte..

This type of titration is carried out between a weak acid such as acetic acid (CH 3 COOH) and weak base such as ammonium hydroxide (NH 4 OH). There is no sharp change in the pH during the titration. Hence, no sharp equivalence point can be obtained with common indic..

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 solution. Greater th..

>Strength of a base depends on the concentration of hydroxyl ions. A strong base dissociates completely in water. Example: Sodium hydroxide A weak base dissociates partially in water. Example: Ammonium hydroxide The acidity of a base is equal to the..

More about Salts - Generally, salts are obtained by treating an acid with a base. Salts consist of both positive ions or 'cations', and negative ions or 'anions'. The cations are called basic radicals and are mostly obtained from metallic ions (ammonium ion b..
