Why is sulfuric acid an oxidising agent?
Why is sulfuric acid an oxidising agent?
The concentrated sulphuric acid can act both as an acid and as an oxidising agent. The concentrated sulphuric acid gives a hydrogen ion to the halide ion to produce a hydrogen halide. Because this is a gas, it immediately escapes from the system.
In which reaction does H2SO4 act as an oxidising agent?
Explanation: since sulohuric acid is strong acid, it will react with weak amphoteric base water and gives H3O±ions in dilute soltions, so sulphuric acid in concerated forms gives nacent oxygen and form sulphurous acid. this nacent oxygen act as oxidising reagent.
Why conc H2SO4 is a good oxidizing agent explain with equation?
concentrated sulphuric acid at higher temperature implies the lesser amount of water content thus it has a stronger power to oxidize other substances, it is all about the rate of reaction occuring.
Can H2SO4 act as both oxidising and reducing agent?
H2SO4 cannot act as reducing agent.
Why is H2SO4 a dehydrating agent?
Sulfuric acid is a dehydrating agent just because it is available in concentrated form whereas rest of the common acids like HCl(aq) are not.
Is Sulphuric acid an oxidizing agent?
Sulfuric acid is not typically regarded as an oxidizing acid because of the stability of the sulfate ion. However, in the presence of sulfur atoms with a lower oxidation state, such as those in sulfides, sulfate can be reduced.
In which reaction H2SO4 not acts as oxidising agent?
Since no reaction happens so the oxidation state of sodium does not change. Hence , in the above reactions the sulphuric acid does not act as an oxidizing agent. So the correct option is ‘D’. 1.
Which of the following element is oxidised by conc H2SO4?
On reacting with hot concentrated H2SO4, C – carbon oxidizes into two gaseous products. The two gaseous products are CO2 and SO2.
Why is H2SO4 not an oxidising agent?
H2SO4 whes hated decomposes to give nascent oxygen which acts as a strong oxidising agent. On the other hand dil H2SO4 on heating does not decompose to give nascent oxygen and as such cannot behave as an oxidising agent.
Why H2SO4 Cannot act as reducing agent?
Sulphur cannot increase its oxidation number beyond +6.
Why H2SO4 is highly viscous?
Sulphuric acid is highly viscous in nature because its molecules are associated with hydrogen bonding. It is a highly corrosive chemical. It is also used as a sulphonating agent in organic reactions.
How does H2SO4 remove water?
Example two. Concentrated sulfuric acid will remove water molecules from glucose molecules (C 6H 12O 6) to leave behind pure carbon. This reaction is highly exothermic and produces a lot of steam which forces the carbon upwards in the reaction vessel.
Why is H2SO4 a strong oxidizing agent?
H2SO4 is a strong acid which reacts by donating an H+ion.Strong acids are proton donors and electron acceptor BY DEFINITION. so H2SO4 will accept an electron during reaction.by accepting an electron it is undergoing reduction so it is an oxidizing agents.
What kind of acid is an oxidizing agent?
An oxidizing acid is a Brønsted acid that is a strong oxidizing agent. All Brønsted acids can act as oxidizing agents, because the acidic proton can be reduced to hydrogen gas. Some acids contain other structures that act as stronger oxidizing agents than hydrogen ion.
How is sulfuric acid stored as an oxidizer?
Concentrated sulfuric acid can be transported and stored in iron containers, as it is molecular and does not readily react with iron. Exactly. This oxidizing strength totally lies within [H+]. Yet conc H2SO4 is a strong oxidant, they haven’t mentioned the [] of the solution itself.
Which is more oxidising sulphuric acid or dilute nitric acid?
Dilute nitric acid (HNO3) is an oxiding agent. Cocentrated nitric acid has greater oxidising power than the dilute acid. Dilute sulphuric acid (H2SO4) is a non-oxidising acid, though the concentrated acid in hot condition acts as an oxidising agent.
