Why nitric acid is strong oxidizing agent than Sulphuric acid?
In the case of Nitric acid (HNO3), the nitrogen has a +5 oxidation state, which is its highest oxidation state, so it will get reduced and oxidize other molecules. Hence it acts as an oxidizing agent.
Why is Sulphuric acid not an oxidizing agent?
Cone. H2SO4 be aves as an oxidising agent because cone. 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 is nitric acid is only a oxidizing agent?
Therefore, nitric acid can only act as an oxidising agent because it itself gets reduced. In case of nitrous acid, the oxidation state of nitrogen is +2. So it can get oxidised to +5 state and also get reduced to -3 state. Thus, it can act as both reducing agent and oxidising agent.
Why nitric acid acts as an oxidising agent only but nitrous acid can act as an oxidising as well as reducing agent?
The oxidation number of nitrogen in HNO3 can only decreasel thus it acts as an oxidising agent. In HNO3 the oxidation number of nitrogen is +3. Thus, it can increase or decrease within the range -3 to +5. Hence it can act as an oxidising as well as reducing agent.
Is nitric acid stronger than Sulphuric acid?
Thus, Sulfuric acid has a stronger pH and is a stronger acid. As both Sulfuric and Nitric acid are strong acids 99+\% usually dissociates in water and Ka isnt a factor; nonetheless, sulfuric acid comes ahead with a Ka around 1000, while Nitric acid is around 2.5.
Which is better oxidising agent HNO3 or H2SO4?
So, with respect to the first pKa for H2SO4, H2SO4 is a stronger acid than HNO3. For pKa2 (HSO4-) it is a weaker acid. But, it is the first pKa that is important, H2SO4 wins on the basis of pKa.
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.
Is sulphuric acid an oxidising agent?
Sulphuric acid acts as an acid, an oxidising agent and as a dehydrating agent. In which way does it behave when it acts on: Sodium hydroxide.
Why is concentrated nitric acid a stronger oxidizing agent than dilute nitric acid?
HNO3 is a stronger oxidising agent than dil HNO3 . It is due to the ease with which cone. HNO3 decomposes to give nascent oxygen which acts as a powerful oxidising agent.
Which of the following acts both as an oxidising as well as reducing agent hno3?
nitrous acid
Nitric acid acts only as an oxidising agent while nitrous acid acts both as an oxidising as well as reducing agent.
Which of the following acts both oxidising and reducing agent hno3?
Since, oxidation number of N in HNO2 is +3, so, it can increase by losing electrons or can decrease by accepting electrons. Hence, HNO2 can act both as reducing and oxidizing agent.
What is the difference between nitric acid and sulfuric acid?
Both nitric and sulfuric are oxidizing, in the narrow academic sense that both react with an electron exchange, but nitric acid is a true oxidizing agent in the sense that it provides free oxygen. The nitrate ion of nitric acid is unstable because of the nitrogen double bond, and resonates between two states.
Why does nitric acid act as an oxidizing agent?
That’s why it acts as oxidizing agent. Yes, Nitric Acid (HNO3) is a very strong oxidizing agent. The reason behind this is that each molecule of nitric acid contains 3 atoms of oxygen. When an acid reacts with a metal, it forms a metallic salt and releases hydrogen gas (H2).
Why does sulfuric acid not produce free oxygen in its reactions?
Although sulfuric acid also has double-bonded oxygen atoms, the bond with sulfur is much more stable than with nitrogen, so its reactions do not generate free oxygen. 8 clever moves when you have $1,000 in the bank.
Why does nitric acid not liberate hydrogen from metal?
Nitric acid is a powerful oxidizing agent and the nascent oxygen formed on decomposition oxidizes hydrogen to water. This is the reason why it does not liberate hydrogen when treated with metals. Under special conditions, when the metal is magnesium (Mg) or manganese (Mn) and the concentration of HNO3 is 1\% that it liberates hydrogen.
