What happens when hydrogen peroxide reacts with acidified k2 cr2 o7?

What happens when hydrogen peroxide reacts with acidified k2 cr2 o7?

Now, when we add hydrogen peroxide to acidified potassium dichromate, hydrogen peroxide will act as an oxidizing agent, as it gets reduced, and its oxidation number changes to -2 from -1 and the chromium present in +6 oxidation state changes to +3 oxidation state.

When H2O2 is added to an acidified K2Cr2O7 solution a green Colour solution is obtained?

gives green precipitate due to the formation of Cr(OH)3.

When Dil h2so4 and H2O2 are added to a solution?

When dilute sulphuric acid and hydrogen peroxide are added to a solution of chromate ions, an intense blue colour is produced which is stable in ether.

When k2 cr2 o7 react with h2 O2 in acidic medium The product will be?

On adding H2O2 in acidic solution of K2Cr2O7, H2O2 oxidisc it to CrO5 (chromic penta oxidc/ chromic per oxide) and gives the blue-violet solution.

When Dil h2so4 and H2O2 are added to a solution of?

chromate ions
When dilute sulphuric acid and hydrogen peroxide are added to a solution of chromate ions, an intense blue colour is produced which is stable in ether.

Does H2O2 have a dipole moment?

The dipole moment of H2O2 is 2.1D while that of water is 1 84D.

When 50\% solution of h2so4 is electrolysed by passing a current of high density at low temperature the main products of electrolysis are?

The correct option is (b) i.e, H2 and peroxy sulphuric acid is obtained in majority .

When dilute h2so4 and H2O2 are added to a solution of chromate ions?

What is the dipole moment of H2O2?

Does CR 3 have color?

Its green. Also for most of the cromium complexes (with cromium in its +3 oxidation state) the colour is green. Moreover it somewhat depends on the type of ligand in the complex.

How many bonds are equivalent in dichromate Dianion?

six Cr−O bonds are equivalent.
