is an indicator the salt of a 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..

This type of titration is carried out between a weak base such as ammonium hydroxide and strong acid such as hydrochloric acid. The equivalence point is below 7 because the salt (NH 4 Cl) formed at the neutralization reacts with water to give H + ions. Th..

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 pre..

This type of titration is carried out between acetic acid and sodium hydroxide. The free H + ion from the weak acid is neutralized by OH - ions from the base and there is a small increase in pH. Around the equivalence point large increase in pH is observed. Howeve..

An acid which dissociates very feebly in water and whose molecules mostly remain in the undissociated form is categorized as a weak acid. It behaves as a weak electrolyte. ..

The amount of an acid (or a base), which is exactly equivalent chemically to the amount of some standard base (or an acid), is determined by an acid-base titration. The point of equivalence is called end point. The solution of a strong acid and strong base w..

Introduction - Acids, bases and salts are three main categories of chemical compounds. These have certain definite properties which distinguish one class from the other. The sour taste of many fruits and vegetables, lemon for instance, is due to various types of acids ..
