Answer 1

Question :

Identify A ,B ,C, D ,E.

a) An acidic gas A which combines with basic gas B to form a sublimable solid C.

b) A greenish yellow gas D having a bleaching action.

c) An acidic gas E which is highly soluble in water.

Solution :

a) An acidic gas A which combines with basic gas B to form a sublimable solid C.

Ammonium chloride (NH₄Cl) is the sublimable solid formed by combination of two gases. One is acidic gas and other is basic gas.

In this reaction, acidic gas refers to HCl (Hydrogen chloride)

And, basic gas refers to NH₃ (Ammonia)

Reaction :

HCl (g) + NH₃ → NH₄Cl (s)

So, A ⇒ Hydrogen chloride (HCl)

B ⇒ Ammonia (NH₃)

C ⇒ Ammonium chloride (NH₄Cl)

Again,

b) A greenish yellow gas D having a bleaching action.

Chlorine gas (Cl₂) is an acidic gas when it combines with water , it forms hypochlorite.

And thus chlorine gas is responsible for bleaching action.

Chlorine gas is a greenish yellow gas.

So, D ⇒ Chlorine gas (Cl₂)

Now,

c) An acidic gas E which is highly soluble in water.

Sulfur dioxide (SO₂) is an acidic gas which is highly soluble is water.

So, E ⇒ Sulfur dioxide (SO₂)

Therefore,

A refers to HCl.

B refers to NH₃

C refers to NH₄Cl

D refers to Chlorine gas (Cl₂)

E refers to Sulfur dioxide. (SO₂)

Chlorine gas (Cl₂) is an acidic gas when it combines with water , it forms hypochlorite.

And thus chlorine gas is responsible for bleaching action.

Chlorine gas is a greenish yellow gas.

So, D ⇒ Chlorine gas (Cl₂)

Now,

c) An acidic gas E which is highly soluble in water.

Sulfur dioxide (SO₂) is an acidic gas which is highly soluble is water.

So, E ⇒ Sulfur dioxide (SO₂)

Therefore,

A refers to HCl.

B refers to NH₃

C refers to NH₄Cl

D refers to Chlorine gas (Cl₂)

E refers to Sulfur dioxide. (SO₂)
