ph of salts

Neutral Salts - A neutral salt arises due to the neutralization reaction. Here, salts of strong acid and strong base combine to form such salts that show a neutral pH of ..

Pure water and other neutral solutions have a pH value of 7. A pH value less than 7 indicates that the solution is acidic, and a pH value greater than 7 indicates that the solution is basic. How does one monitor these pH changes? By using substances called in..

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 basic salt may also be formed by the partial replacement of the hydroxyl groups of a diacidic or triacidic base, by an acid radical. Basic salts are stronger in their basic nature and show a pH greater than ..

Dissolution of different salts in water does not always result in neutral solutions. For example, aqueous solution of copper sulphate is acidic whereas aqueous solution of sodium acetate is basic and aqueous solution of sodium chloride forms neutral solution. This is due to the dissociati..

>A strong base dissociates completely in water Example: Sodium hydroxide A weak base dissociates partially in water Example: Ammonium hydroxide In neutralization reaction acids and bases neutralize each other to form corresponding salts and water Acidic and basic solutions yield ions in s..

On heating, hydrous crystals lose their water of crystallization and turn into a powder. They are then said to be anhydrous. Sometimes they may also lose their colour. ..

Substitution of Diazonium Salts - This is a convenient method of preparation of aryl cyanides only. It is not suitable for preparing alkyl cyanides because alkyl diazonium salts are quite unstable even at low temperatures. It involves the treatment of benzene diazonium salt..

When ammonia is passed through aqueous solutions of certain salts, the respective metallic hydroxides are precipitated. In the case of salts of copper, the blue precipitate of copper hydroxide formed dissolves in excess of ammonia solution to give a deep blue soluti..
