(i). For a weak monobasic acid K_(a)=10^(_5) and pH=5 then degree of dissociation of acid is 50% (ii). [H_(2)SO_(4)]=0.1M" "V=400ml [NaOH]=0.1M" "V=400ml on mixing these solution pH is approximately 1.3 (iii). Ionic product of water depends on temeprature (iv). Le-chatelier's principal is not applicable for common ion effect. Select the correct options:

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?

Give the common effects of radioactive pollution. List the steps for its control.

Assertion : Benzyl carbonium ion is more than tertiary carbonium ion. Reason : In Benzy I carbonium + I effect is more in comparison to tertiary carbonium ion.
