Why is SO3 not directly absorbed in water to get sulfuric acid?

The correct answer of this question is option ‘c’, sulphur trioxide is not directly dissolved in water to form sulphuric acid because it results in the formation of dense fog of sulphuric acid which is difficult to condense.

Why is SO3 not directly absorbed by water?

SO3 dissolution in water is extremely exothermic. This forces the sulfuric acid to form a mist of tiny droplets. These are highly corrosive which can even attack and corrode the lead pipelines and linings which cover the tower in contact process. Also, this mist does not condense so easily.

What happens when sulphur trioxide is dissolved in water?

It can react with water to form sulfuric acid. SO3 is also called sulfuric oxide and sulfuric anhydride. It is used in the production of sulfuric acid and other chemicals, and explosives.

How is Sulphur trioxide changed to sulphuric acid?

Adding an excess of oxygen to sulfur dioxide in the presence of the catalyst vanadium pentoxide at 450 °C and 1-2 atm. The sulfur trioxide formed is added to sulfuric acid which gives rise to oleum (disulfuric acid) The oleum is then added to water to form sulfuric acid which is very concentrated.

Why is Sulphur trioxide dissolved in concentrated sulphuric acid?

SO3 dissolution in water is extremely exothermic… when dissolved in water sulphur trioxide forms a mist of sulphuric acid which can be difficult to store and handle.. bcoz of this in order to form sulphuric acid an intermediate called oleum must be formed where SO3 is dissolved in H2SO4 giving H2S2O7.

Why is sulphur trioxide dissolved in concentrated sulphuric acid?

Is SO3 soluble in water?

To form an aqueous solution of sulfuric acid (H2SO4), sulphur trioxide (SO3) dissolves in and reacts with water.

When Sulphur is dissolved in water then?

Answer : When sulphur dioxide is dissolved in water, then it forms sulphurous acid (H2SO3). Explanation: Metals react with oxygen to form metallic oxides. These metallic oxides are basic in nature because they react with water to form bases.

Why is so2 formed instead of so3?

Since they are formed by the interaction between sulphur and O2 molecules, these compounds are called sulphur oxides. The key contrast between SO2 and SO3 is that SO2 has two atoms of oxygen bonded to a sulphur atom, whereas SO3 has three atoms of oxygen bonded to a sulphur atom.

Why does sulfuric acid react with water?

Sulfuric Acid and Water Safety Water is less dense than sulfuric acid, so if you pour water on the acid, the reaction occurs on top of the liquid. If you add the acid to the water, it sinks.

Why is sulfur trioxide not directly dissolved in water to form sulphuric acid?

Sulphur trioxide is not directly dissolved in water to form sulphuric acid because. Becuase when sulfur trioxide mixed with water it leads to the formation of dense fog of sulphuric acid which is difficult to condense

What is the contact process of sulfuric acid?

Hint: Contact process is the industrial method of producing sulphuric acid. It is also called lead-chamber process. Sulphur dioxide and oxygen combines to form sulphur trioxide, which reacts with water to form sulphuric acid. Why Platinum is not used in contact process?

What happens when SO3 is dissolved in H2SO4?

Because of this, in order to form sulfuric acid, an intermediate called “oleum” must be formed, where SO3 is dissolved in H2SO4, giving H2S2O7. This is then dissolved in water to form sulfuric acid.

How do you make sulfuric acid from SO3?

Because of this, in order to form sulfuric acid, an intermediate called “oleum” must be formed, where SO3 is dissolved in H2SO4, giving H2S2O7. This is then dissolved in water to form sulfuric acid.
