In the reaction $ 2Ag + 2H_2SO_4 \rightarrow Ag_2SO_4 + 2H_2O + SO_2, H_2SO_4 $ acts as
In the given reaction, $ H_2SO_4 $ acts as an oxidizing agent. Silver ( $Ag$ ) is oxidized to $Ag_2SO_4$ , while $ H_2SO_4 $ is reduced to $SO_2$ . This indicates that $H_2SO_4$ is acting as an oxidizing agent.
In the reaction $ HCOOH \rightarrow [] { { H_2 SO_4}} CO + H_2O, H_2SO_4 $ acts as
In the reaction $ HCOOH ightarrow [] { { H_2 SO_4}} CO + H_2O $ , sulfuric acid ( $H_2SO_4$ ) acts as a dehydrating agent. It removes water ( $H_2O$ ) from formic acid ( $HCOOH$ ) to form carbon monoxide ( $CO$ ). Thus, $H_2SO_4$ is functioning as a dehydrating agent.
When $ conc.H_2SO_4$ comes in contact with sugar it becomes black due to
When concentrated sulfuric acid ($conc.H_2SO_4$) comes into contact with sugar, it acts as a strong dehydrating agent. It removes water (H_2O) molecules from the sugar (C_12H_22O_11), leaving behind carbon (C), which appears black. Hence, the correct answer is dehydration.
Which one is known as oil of vitriol
Oil of vitriol is the common name for sulfuric acid ($H_2SO_4$). This name dates back to the alchemists who called it so due to its oily appearance and strong corrosive properties. Hence, the correct answer is $H_2SO_4$.
Ozone deplete due to the formation of following compound in Antartica
Fromation of chlorine nitrate is the main cause of ozone depletion
The acid used in lead storage cells is
Sulfuric acid ($H_2SO_4$) is used in lead storage batteries. It acts as the electrolyte in the battery, enabling the flow of electric current. Hence, the correct answer is sulfuric acid.
Which one of the gas dissolves in $ H_2SO_4$ to give oleum
$ H_2SO_4 + SO_3 \rightarrow H_2S_2O_7 $ oleum.
Oleum is
Oleum is also known as fuming sulfuric acid, which is represented chemically as H₂SO₄ with additional sulfur trioxide (SO₃). It is a solution of sulfur trioxide in sulfuric acid and is used in various industrial processes.
