Dissociation of an electrolyte in water into negative and positive ions is called

The concept of cmmon ion effect applies to the dissociation of weak electrolytes. Their dissociation gets further suppressed in the presence of common ions furnished by a suitable electrolyte. Similarly the solubility of sparingly soluble salts in water gets suppresessed by the presence of a common ions. You are provided with an aqueous solution containing Cu^(2+) " and " Zn^(2+) ions. (i) How are these ions precipitated from the solution (ii) What is the colour of the precipiate formed ? (iii) How does dilute HCI help in checking the precipitation of Zn^(2+) ions in group II? (iv) How does NH_(4)OH help in promoting the precipitation of Zn^(2+) ions in group IV?

The degree of dissociation of an electrolyte does not depend on

Statement : The dissociation constants of polyrotic acid are in the order K_(1)gtK_(2)gtK_(3) . Explanation : The [H^(+)] furnished in first step of dissociation exerts common ion effect to reduce the secend dissociation so on.
