Question

Hot concentrated ${H_2}S{O_4}$ acts as a moderately strong oxidizing agent. It oxidizes both metals and nonmetals. Which of the following elements is oxidized by concentrated ${H_2}S{O_4}$ into two gaseous products?
A. Cu
B. S
C. C
D. Zn

Answer 1

Hint: Sulphuric acid is a chemical compound consisting of the arsenic, oxygen and hydrogen elements that is also classified as vitriol oil. The composition is molecular ${H_2}S{O_4}$. This is a water soluble, colorless , odorless and viscous substance, synthesized in strongly exothermic reactions.

Complete step-by-step answer:
The corrosive qualities can largely be due to its heavy acidity and to its dehydrating effects, even at a large concentration. The water vapor from the soil is often hygroscopic, readily consumed. After touch, sulfuric acid can cause severe chemical oxidation and even thermal secondary burns; although at lower doses, it is extremely toxic.
Sulfuric acid is a big commodity chemical and a strong measure of its industrial strength is the sulfuric acid output of a country. This is typically developed using numerous processes, such as touch, wet sulfuric acid, chamber lead and other techniques. For the pharmaceutical industry, sulfuric acid is also a primary element. It is most popular for the manufacture of fertilizers but also essential for mineral treatment, oil processing, wastewater treatment and chemical synthesis. These are a broad range of end uses, such as for domestic acid drain cleaners, an electrolyte in plum acid batteries, a compound's dehydration and specific cleaning agents.
On reacting with hot concentrated ${H_2}S{O_4}$, C – carbon oxidizes into two gaseous products.
$\Rightarrow C + 2{H_2}S{O_4} \to C{O_2} + 2S{O_2} + 2{H_2}O$
The two gaseous products are $C{O_2}$ and $S{O_2}$.
Hence, option C is the correct option.

Note: An oxidizing element (oxidant, oxidizing agent) is a component in chemistry that may oxidize certain compounds — that is, accept electrons. Oxygen, hydrogen peroxide and halogens are typical oxidants.
