In acidic medium, potassium dichromate acts as:
Correct answer: A. Oxidizing agent
- A. Oxidizing agent
- B. Reducing agent
- C. An Acid
- D. A base
Explanation
Potassium dichromate is commonly used as an oxidizing agent in acidic medium. In acidic conditions, it can undergo reduction, thereby oxidizing other substances. The dichromate ion (Cr2O72-) is reduced to chromium(III) ions (Cr3+), while itself being reduced. This is the primary function of potassium dichromate in acidic medium.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
