Is K2Cr2O7 a strong oxidizing agent?

Potassium dichromate is a powerful oxidizing-agent, especially in an acidic medium. This chemical compound is commonly used to oxidize alcohols.

Is K2Cr2O7 a strong reducing agent?

Potassium dichromate is indeed a powerful oxidizing agent. The orange salt features Cr(VI+), and is typically reduced to Cr(III+), a green salt…

Is K2Cr2O7 a reducing agent or oxidizing agent?

Potassium dichromate is an oxidising agent in organic chemistry, and is milder than potassium permanganate. It is used to oxidize alcohols. It converts primary alcohols into aldehydes and, under more forcing conditions, into carboxylic acids.

Which is strong oxidizing agent K2Cr2O7 or KMnO4?

The KMnO4 is stronger oxidizing agent than k2Cr2O7 because due to its higher reduction potential since as we know that the compound having higher reduction potential behaves as best oxidizing agent . Here reduction potential value of KMnO4 is +1.52V and K2Cr2O7 has +1.33V .

Is HNO3 an oxidizing agent?

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. Hence it is a strong oxidizing agent.

Is HNO3 oxidizing or reducing agent?

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.

What is the oxidation number of K2Cr2O7?

Let x be the oxidation number of two chromiums. So, two chromium atoms have an oxidation number of +12. So one chromium atom will have an oxidation number of +12 /2=+6. So oxidation number of Cr in K2Cr2O7 is +6.

Why K2Cr2O7 is strong oxidizing agent in acidic medium?

In acidic medium, Cr undergoes a decrease in oxidation state from +6 in Cr2O2-7 ion to +3 in Cr3+ ion. Since +3 oxidation state is more stable than +6 oxidation state therefore, K2Cr2O7 is a good oxidising agent in the acidic medium.

Which of the following is most powerful oxidizing agent in the following a KMnO4 B K2Cr2O7 C o3?

KMnO4 is a stronger oxidising agent than K2Cr2O7 .

Which among the following is the strongest oxidising agent at high concentration HNO3?

Nitric acid is a powerful oxidizing agent and the nascent oxygen formed on decomposition oxidizes hydrogen to water. Yes Nitric acid is a strong oxidizing agent.
