Which of following is a very powerful oxidant:
Correct answer: B. Dichromates
- A. Sulphates
- B. Dichromates
- C. Nitrates
- D. Chromates
Explanation
Dichromates, specifically potassium dichromate (K2Cr2O7), are powerful oxidizing agents. They are commonly used in organic chemistry as oxidizing agents in various reactions. Dichromates contain the Cr(VI) ion, which readily accepts electrons, causing the reduction of another substance.

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.
