Write a balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution. Be sure to add physical state symbols where appropriate.

The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:

Explanation:

The reaction :

Balancing of reaction in an acidic medium:

Step 1: Balance the atoms in the reaction:

Step 2: Balance oxygen atom by adding water on the side where no oxygen or less oxygen atom is present;

Step 3: Balance the hydrogen atom by adding  hydrogen ions on the side where water is absent:

Step 4: Now balance charge by adding electrons on the side where more positive charge is present

The balanced half-reaction for the reduction of dichromate ion to chromium ion in acidic aqueous solution:

answer: mole of the gas

answer: mole of the gasexplanation:
