Chemistry Class 12 Question Paper

 SECTION – A
Read the given passage and answer the questions 1 to 5 that follow :
 
Colloidal particles always carry an electric charge which may be either positive or negative. For example, when AgNO3 solution is added to KI solution, a negatively charged colloidal sol is obtained. The presence of equal and similar charges on colloidal particles provide stability to the colloidal sol and if, somehow, charge is removed, coagulation of sol occurs.
Lyophobic sols are readily coagulated as compare to lyophilic sols.
 
1. What is the reason for the charge on sol particles ?
 
2. Why the presence of equal and similar charges on colloidal particles provide stability ?
 
3. Why a negatively charged sol is obtained on adding AgNO3 solution to KI solution ?
 
4. Name one method by which coagulation of lyophobic sol can be carried out.
 
5. Out of KI or K2SO4, which electrolyte is better in the coagulation of positive sol ?
 
Questions 6 to 10 are one word answers :
 
6. Name the method applied for the concentration of Bauxite ore in the extraction of Aluminium.
 
8. Write an isomer of C3H9N which gives foul smell of isocyanide when treated with chloroform and ethanolic NaOH.
 
9. Which one of the following is an antidepressant drug ?
Chloramphenicol, Luminal, Bithional
 
10. Write the name of component of starch which is water soluble.

13. The slope in the plot of ln [R] Vs. time gives
(a) + k         (b) + k /2.303
 
(c) – k         (d)  – k /2.303
 
(where [R] is the final concentration of reactant.)
 
14. The pair [Co(NH3)4 Cl2] Br2 and [Co(NH3)4 Br2] Cl2 will show
 
(a) Linkage isomerism              (b) Hydrate isomerism
(c) Ionization isomerism           (d) Coordinate isomerism
