Solution

The correct options are
A
Sulphur dioxide and bromine water

C
Sulphuryl chloride with water

Sulphuric and hydrobromic acid is formed in option A whereas sulphuric and hydrochloric acid formed in option C. Fluorine reacts with water violently so there "fluorine water" makes no sense. Since nitric acid undergoes reduction, only one acid is formed in option D.

$C l_{2} + 2 H_{2} O + S O_{2} ⟶ 2 H C l + H_{2} S O_{4}$

$B r_{2} + 2 H_{2} O + S O_{2} ⟶ 2 H B r + H_{2} S O_{4}$

$S O_{2} C l_{2} + 2 H_{2} O ⟶ 2 H C l + H_{2} S O_{4}$

$S + c o n c . 6 H N O_{3} ⟶ 6 N O_{2} + H_{2} S O_{4} + 2 H_{2} O$

Q. Why does sulphur on reacting with concentrated nitric acid gives sulphuric acid instead of sulphur dioxide?

Carbon dioxide and sulphur dioxide, when treated with water form their respective acids.

Q. A water soluble salt 'P' on reaction with sulphuric acid gives the products 'Q', carbon dioxide and water. Identify P and Q.

Give reasons for the following:
(i) In the contact process, sulphur trioxide formed is dissolved in 98% sulphuric acid and not in water.
(ii) When solution of sulphur dioxide is exposed to air, it gets converted to sulphuric acid.
(iii) When diluting concentrated sulphuric acid, the acid should be added to water and not water to the acid.
(iv) When concentrated sulphuric acid is exposed to air, its volume increases and it becomes slightly dilute.
(v) Sulphuric acid can form two kinds of salts with sodium chloride.
(vi) When barium chloride is added to dilute sulphuric acid, a white precipitate is formed.
(vii) When carbon is heated with concentrated sulphuric acid, carbon dioxide is formed.
(viii) Ammonia gas cannot be dried by passing through concentrated sulphuric acid.
(ix) When concentrated sulphuric acid is added to sugar/glucose, a black mass is left behind.
(x) Concentrated sulphuric acid should not be added to oxalic acid or formic acid in the open laboratory.
(xi) When concentrated sulphuric acid is added to blue crystalline copper sulphate, it turns powdery white.
(xii) Concentrated sulphuric acid must be stored in airtight bottles.
(xiii) Cotton clothes get burnt with concentrated sulphuric acid.
(xiv) H₂SO₄ cannot be prepared by heating sodium sulphate with conc. HCl or HNO₃.
