Solution

  1. Cr2O72- is an oxidizing agent.
  2. A chemical called acid is nothing more than a substance that, according to Arrhenius' principle, dissociates to produce hydrogen ions when broken down in the water.
  3. Hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3) are some examples of Arrhenius acids.
  4. According to Arrhenius thought, a chemical that dissociates to produce a hydroxyl ion when broken down in the water is called a base.
  5. Sodium hydroxide (NaOH), calcium hydroxide (Ca(OH)2), and other hydroxides are examples of Arrhenius bases.
  6. The hydrogen dichromate(H2Cr2O7), which can transfer protons, is acidic according to the Arrhenius view.
  7. Due to its ability to accept protons, the dichromate ion Cr2O7 serves as the conjugate base of hydrogen dichromate.
  8. The following chemical reaction is related to the above topic,

H2Cr2O7(aq)Cr2O72-(aq)+2H+(aq)

Considering the above argument, we conclude that Cr2O7 is a base.

Hence, Cr2O72- a base.
