Advantages of potassium dichromate over potassium permanganate in volumetric analysis

• Hydrochloric acid can be used to acidify titration involving potassium dichromate since are not strong oxidizing agents to oxidize chloride ions to chlorine like permanganate (VII) would do.
• Potassium dichromate can obtained in stable pure form.
• Potassium dichromate ions form stable solution
