AP Inter 2nd Year Chemistry Answer Key 2024

SECTION - A

1.What are isotonic solutions?

Answer: The solutions having the same osmotic pressure at a given temperature are called isotonic solutions. For example, the osmotic pressure associated with fluid inside the blood cell is equivalent to that of 0.9%  NaCl solution thus they are isotonic solutions.

2.What is a primary battery? Give one example.

Answer: The batteries which after their use over a period of time, become dead and  cannot be recharged, are known as primary batteries. For example: dry cells. 

3.State the role of silica in the metallurgy of copper.

Answer: The role of silica in the metallurgy of copper is to remove the iron oxide obtained as slag during the process of extraction of pure copper from copper pyrite.

4.How is chlorine manufactured by Deacon's method?

Answer: In Deacon's process chlorine is obtained by the oxidation of hydrogen chloride gas by atmospheric oxygen in the presence of  CuCl₂ (catalyst) at 723 K.

5.What happens when Cl₂ reacts with dry slaked lime?

Answer: Chlorine reacts with dry slaked lime to produce water and calcium oxychloride, commonly known as bleaching powder.

6.Calculate the spin only magnetic moment of Fe²⁺aq ion.

Answer:

Magnetic moment is given by, μ=√[n(n+2)]

In Fe²⁺, 4 unpaired electrons are present.

Therefore, μ = μ=√[4(4+2)]= √24 BM =4.90 BM

7.What is vulcanization of rubber?

Answer: Vulcanization of rubber is the process of converting natural rubber to a more strong and elastic form. It includes cross-linking rubber molecules chemically with organic/inorganic substance through the action of heat and pressure. 

8.What is Ziegler-Natta catalyst?

Answer: Ziegler-Natta catalyst is a mixture of titanium tetrachloride TiCl₄ and triethyl aluminium chloride Al(C₂H₅)₃. It is used in the synthesis of polymers of 1-alkenes (alpha-olefins).

9.What are antacids? Give example.

Answer: An antacid is a chemical compound, which neutralizes excessive hydrochloric acid released in the stomach. For example,  sodium bicarbonate.

10.What is the difference between a soap and a synthetic detergent?
