317027 The key step in the manufacture of \(\mathrm{H}_{2} \mathrm{SO}_{4}\) is

1 Burning of sulphur or sulphide ores in air to generate \(\mathrm{SO}_{2}\).
2 Catalytic oxidation of \(\mathrm{SO}_{2}\) with \(\mathrm{O}_{2}\) to give \(\mathrm{SO}_{3}\) in the presence of \(\mathrm{V}_{2} \mathrm{O}_{5}\).
3 Absorption of \(\mathrm{SO}_{3}\) in \(\mathrm{H}_{2} \mathrm{SO}_{4}\) to give oleum.
4 Either (2) or (3)

317028 Sulphuric acid has great affinity for water because

1 It hydrolyses the acid
2 It decomposes the acid
3 Acid decomposes water
4 Acid forms hydrates with water
CHXI11:THE P-BLOCK ELEMENTS

317029 The reactions in which conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\) is used as an oxidising agent are
I. \(2 \mathrm{HI}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{I}_{2}+\mathrm{SO}_{2}+2 \mathrm{H}_{2} \mathrm{O}\)
II. \(\mathrm{NaCl}+2 \mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{NaHSO}_{4}+\mathrm{HCl}\)
III. \(\mathrm{CaF}_{2}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{CaSO}_{4}+2 \mathrm{HF}\)
IV. \(\mathrm{Cu}+2 \mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{CuSO}_{4}+\mathrm{SO}_{2}+2 \mathrm{H}_{2} \mathrm{O}\)
Choose the correct option.

317030 A student accidentally splashes few drops of conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\) on his cotton shirt. Then the splashed parts get blackened and the holes appear. This happens because sulphuric acid

1 heats up the cotton
2 removes the elements of water from cotton
3 causes the cotton to react with water
4 oxidising the cotton with burning
