Question

Is ${\mathrm{K}}_2{\mathrm{Cr}}_2{\mathrm{O}}_7$ paramagnetic?

Answer 1

Explanation:

${\mathrm{K}}_2{\mathrm{Cr}}_2{\mathrm{O}}_7$ is a diamagnetic material, the electron structure can be used to determine the magnetic properties of materials, if there are unpaired electrons, the substance is paramagnetic, and if all electrons are paired, the material is diamagnetic.

1. It is a crystalline ionic solid with a bright red-orange colour.
2. The salt is common in the laboratory because it is not flavorful, unlike the more industrially important sodium dichromate salt.
3. Dichromate acid is a potassium salt potassium dichromic is a salt of potassium. It acts as an oxidizing agent, an allergen, and a sensitizer. This requires the use of a dichromate which is in (2-) valence state.

Hence, ${\mathrm{K}}_2{\mathrm{Cr}}_2{\mathrm{O}}_7$ is diamagnetic.
