Question

Give two balanced reactions to show the following properties of sulphuric acid: Oxidising agent.

Answer 1

Hint: Sulfuric acid, commonly known as oil of vitriol, is a mineral acid with the chemical formula $ {{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}} $ and is made up of the elements sulphur, oxygen, and hydrogen. It's a colourless, odourless, viscous liquid that's water miscible. Because of its great affinity for water vapour, pure sulfuric acid does not exist naturally on Earth; as a result, it is hygroscopic and quickly collects water vapour from the air.

Complete answer:
An oxidising agent (oxidant), sometimes known as an oxidising agent (oxidiser), is a chemical that has the capacity to oxidise other compounds by accepting their electrons. Oxygen, hydrogen peroxide, and halogens are common oxidising agents. In one definition, an oxidising agent is a chemical entity that acquires one or more electrons through a chemical process. In that respect, it's a part of a redox (oxidation–reduction) process. An oxidising agent is a chemical species that transfers electronegative atoms, generally oxygen, to a substrate in the second sense.
In electron-transfer processes, electron acceptors play a role. The oxidising substance is referred to as an electron acceptor, whereas the reducing agent is referred to as an electron donor. An oxidising agent is a substance that transfers oxygen atoms to a substrate. The oxidising agent is also known as an oxygenation reagent or an oxygen-atom transfer (OAT) agent in this context.
Oxidising agent:
 $ \mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{H}_{2} \mathrm{O}+\mathrm{SO}_{2}+[\mathrm{O}] $
Non-metals, metals, and inorganic substances are all oxidised by nascent oxygen.
 $ \mathrm{C}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O}+2 \mathrm{SO}_{2} $
Sulphur to sulphur dioxide.
 $ \mathrm{S}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow 3 \mathrm{SO}_{2}+2 \mathrm{H}_{2} \mathrm{O} $ .

Note:
Sulfuric acid is an essential commodity chemical, and its production is a strong measure of a country's industrial strength. It's made in a variety of ways, including the contact process, wet sulfuric acid process, lead chamber technique, and others. In the chemical sector, sulfuric acid is also important. It's most prevalent in fertiliser production, but it's also employed in mineral processing, oil refining, wastewater treatment, and chemical synthesis.
