Could you use KMnO4 instead of K2Cr2O7 and what advantage does K2Cr2O7 has over KMnO4?

KMnO4 is a stronger oxidising agent than K2Cr2O7 .

What is difference between K2Cr2O7 and KMnO4?

Summary – Potassium Permanganate vs Potassium Dichromate Potassium permanganate and potassium dichromate are potassium salts. The key difference between potassium permanganate and potassium dichromate is that potassium permanganate has a dark violet colour, whereas potassium dichromate has a red-orange colour.

Which is a better oxidant KMnO4 or K2Cr2O7 in acid medium?

KMnO4 is slightly stronger oxidising agent than K2Cr2O7 in acidic medium due to its higher reduction potential since the compound having higher reduction potential behaves as best oxidizing agent.

Why K2Cr2O7 is strong oxidizing agent?

Potassium dichromate is a good oxidizing agent because when elements come into its contact in a chemical reaction they become more electronegative as their atom’s oxidation state increases.

What is the advantage of using KMnO4 solution?

The aqueous solutions are quite stable towards light. It is thus an excellent primary standard and its standard solutions can be prepared by direct weighing of an amount of it and dissolving in a known volume of distilled water.

What are the advantage of using KMnO4?

Potassium Permanganate is a versatile and powerful oxidant that can be used to determine many substances by direct or indirect titration. A unique advantage of Potassium Permanganate is that it serves as its own indicator. Titrations with Permanganate must be carried out in strong acid solution.

Is K2Cr2O7 a reducing agent or oxidizing agent?

The element chromium (Cr) is present in the compound Cr2O2−7. Potassium dichromate is a good oxidizing agent, in the acidic medium the oxidation state of chromium changes by +3.

Which is stronger K2Cr2O7 or KMnO4?

Answer Expert Verified. 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 .

Why KMnO4 is used in titration?

Determining the Concentration of an Analyte Permanganate Titration EndpointA redox titration using potassium permanganate as the titrant. Because of its bright purple color, KMnO4 serves as its own indicator. Note how the endpoint is reached when the solution remains just slightly purple.

Can you use KMnO4 instead of K2Cr2O7 which is stronger oxidizing agent?

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 .
