Sample Questions

(1) A bottle of H3PO4 solution contains 70% (w/w) acid. If the density of the solution is 1.54 g cm-3, the volume of the H3PO4 solution required to prepare 1 L of I N solution is
(A) 90 mL
(B) 45 mL
(C) 30 mL
(D) 23 mL

(2) Wood or cattle dung ash is used for cleaning cooking utensils in many parts of India. The statement that is not true for this ash is:
(A) it largely consists of metal oxides and silicates because non-metals are removed as gaseous compounds during burning of the wood/dung cakes.
(B) when added to water, it forms alkaline solution with pH~8 and above, which helps to remove oily substances from the utensils.
(C) several chemical components of ash remain undissolved as solids in water and these solids help in cleaning by providing scrubbing action.
(D) if left moist for a few hours in air, it slowly turns acidic because of oxidative decomposition

3. When 1 L of 0.1 M sulphuric acid solution is allowed to react with 1 L of 0.1 M sodium hydroxide solution, the amount of sodium sulphate (anhydrous) that can be obtained from the solution formed and the concentration of H+ in the solution respectively are
(A) 3.55 g, 0.1 M

(D) 7.10 g, 0.05 M

4. A current of 5.0 A flows for 4.0 h through an electrolytic cell containing a molten salt of metal M. This results in deposition of 0.25 mol of the metal M at the cathode. The oxidation state of M in the molten salt is (1 Faraday = 96485 C mol-1)

(A) 82 (B) 85 (C) 88 (D) 92

8. Sodium metal dissolves in liquid ammonia and forms a deep blue solution. The color is due to absorption of light by
