Fill in the blank: Sulfuric acid can be prepared by the dissolution of sulfur trioxide (SO3) in ___ .

Water

True or False: Sulfuryl chloride (SO2Cl2) can be hydrolyzed to produce sulfuric acid and hydrochloric acid.

True

By passing chlorine gas through an aqueous solution of sulfur trioxide, what acid is produced?

Sulfuric acid (H2SO4) is produced along with hydrochloric acid (HCl).

Fill in the blank: The reaction Cl2 + SO2 + 2 H2O → 2 HCl + ___ produces sulfuric acid.

H2SO4

Fill in the blank: Sulfur trioxide (SO3) is absorbed by concentrated sulfuric acid to form ___, also known as pyrosulfuric acid.

Oleum

True or False: The oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3) occurs at a temperature of 150°C in the presence of vanadium pentaoxide.

False. The oxidation occurs at 450°C.

What is the role of vanadium pentaoxide in the contact process?

Vanadium pentaoxide acts as a catalyst to facilitate the oxidation of sulfur dioxide (SO2) to sulfur trioxide (SO3).

Fill in the blank: The purification of gases in the contact process is important to enhance the efficiency of the ___ used.

Catalyst

Describe the chemical reaction that produces sulfur dioxide in the contact process.

Sulfur dioxide is produced by the roasting of iron disulfide (FeS2) in the presence of oxygen, according to the reaction 4FeS2 + 11O2 → 2Fe2O3 + 8SO2.

Dilute sulphuric acid reacts with metals to produce ___ and ___.

Dilute sulphuric acid reacts with metals to produce metallic sulphates and hydrogen.

True or False: Concentrated sulphuric acid can act as a dehydrating agent due to its high affinity for water.

True.

Fill in the blank: Concentrated sulphuric acid is used to prepare volatile acids like ___ and ___ from their salts.

HCl and HNO3.

How does dilute sulphuric acid interact with metallic carbonates?

Dilute sulphuric acid liberates carbon dioxide from metallic carbonates and bicarbonates, forming metallic sulphates, water, and carbon dioxide.

What is one of the primary industrial uses of sulphuric acid in relation to fertilizers?

Sulphuric acid is used in the manufacture of fertilizers such as ammonium sulphate and superphosphate of lime.
